We use dots because not all the numbers on the graph are in her bank account

# data[].attributes.body
They wouldnt use a line graph because she only deposits $5 a week not like $12 or $13 it counts by 5

# data[].attributes.body
The graph doesn ot make a line because, as opposed to showing a linear trend or progression with many points in between, the graph is portraying a few selct points within a domain, or any unit. By making a line, that would be showing the points are continuous, yet independent events. In addition, all of the points between each dot will or may not occur.

# data[].attributes.body
We don't always use lines to connect the points because not all the nunmbes in between the plotted points apply to the data that has been graphed.

# data[].attributes.body
the reason they dont put it with a line is because she only adds 5 dollars every week. not 3 or 2. so the reason the graph isnt drawn with a line is because a line hits every point inbetween the 5 dollars while but we only need/have the 5 dollars to add each week.

# data[].attributes.body
They used dots instead of a straight line on the graph because each dot represented a specific point. The pattern was that each week she added 5 dollars to her account. Since there was never a time when she was adding less than 5 dollars, randomly, then a line would not apply. A line, instead, would imply that she was adding random amounts of money at random times. Since there is a consistent pattern, the dots show that they are on the only point possible each week.

# data[].attributes.body
I also think that we used plotted points instead of lines because the plotted points were plotted spescifically for the point itself, not any thing in between each point. There is no possible points between the original points. I think that the lines would mean  that there would be a possible point between the points. This is not possible.

We use dots because it doesn't make sense to make a line. This is because Beth will never deposit an amount lower than or greater than 5 dollars. Thus, she will not have a line because she will never have anything other than a multiple of 5. She will never have anything like 10 1/2 so it would make no sense to graph it.

Also, Beth will probably not be putting in 5 dollars in for the rest of her life. The line wont continue forever and hasnt started in the begginning of time.

# data[].attributes.body
Dots were used to do this graph because it dosnt maks sense to connect to points that are not whole numbers that are not in the domain of w. They would use the dots to graph this because there can only be multiples of five in here account.

# data[].attributes.body
there is no line because she does not deposit any money not in between each week or domain so they are not connected by lines and not every number is a part of the graphed data

# data[].attributes.body
We use dots because she does not deposit the amount in between the dots. If there was a line it would show that she was depositing at $11, $12, $13 and so on, which in not true.

# data[].attributes.body
Dots are used instead of a line because if there is a straight line, parts of the line that the line go through will not make any sense towards the graph.

# data[].attributes.body
The dots are not connected because it is not one continus payment she makes payments once a week and that is shown by the dots. There are not payments that are happening between the dots that is why nothing is shown. She is only making payments  of 5 dollars

# data[].attributes.body
we use dots because not all numbers are on the domain, not all numbers are graphed

# data[].attributes.body
because she won't pay forever

# data[].attributes.body
The dots aren't connected because they didn't deposit the money continuously, they deposited the money once at a time

# data[].attributes.body
There were no lines connecting the dots because it is easier to read the graph

# data[].attributes.body
they do not make lines in between the dots becuase numbers such as 2 1/2 are not in the domain of w.

# data[].attributes.body
The book did not draw a line on the dots because the "linear equation" shows that all the plots on the graph lie on the same line. Certain numbers don't connect because they aren't part of the domain and it would be pointless to connect the dots. For example, 2 1/2 doesn't go with the domain W here was not any number that could be used.

# data[].attributes.body
The points on the graph are not connected because there are no numbers that are meant to go inbetween the the points on the graph.

# data[].attributes.body
The reason that you dont connect the dots is that not all the nubers are in the domian of
w

# data[].attributes.body
The dots are used because even though that we are depositing money every day, there would be a line connecting all of the dots if we deposit money at every single chance we can get.
a number like 3.5 can not interlock with a whole number like 7.

# data[].attributes.body
We use dots instead of connecting them together into lines because the "linear equation" shows that all the plots on the graph, lie on the same line. Certain numbers don't connect because they aren't part of the domain and it would be pointless to connect the dots. For example, 2 1/2 doesn't go with the domain W

# data[].attributes.body
The reason they don't use a line and only dots is, because she is only putting 5 dollars in at different times, not forever

# data[].attributes.body
The dots are used because although the graph shows deposit over time, she does not deposit money every second. Instead, she deposits money at certain points in time, which is why the dots don't have the connecting lines.

# data[].attributes.body
Because when you connect the dots on the graph, you are saying that all the numbers the line goes through is a solution. A number like 2.5 might not be a solution.

# data[].attributes.body
They didnt use lines beacuse the interval w is whole numbers, and because numbers such as 2 1/2 woudn't make sense since they aren't in the domain of w (whole numbers).

# data[].attributes.body
When you are depositing money on a weekly basis the dots on your graph will go up and to the right. The reason why we use dots is for you wont deposit anything more then lets say five dollars and you will only do it once a week so if you did a line it would be like saying that you deposit different amounts of money everyday, which you dont, so use dots.

We use dots instead of connecting them together into lines because the "linear equation" shows that all the plots on the graph, lie on the same line. Certain numbers don't connect because they aren't part of the domain and it would be pointless to connect the dots. For example, 2 1/2 doesn't go with the domain w.
