https://padlet.com/csmith160/5a38yg8aeayp This activity is inspired by the notion that mathematics can be found all around us if we just take the time to look for it. Refer to my example below and then create your own post using the following instructions 1) Take a picture of any example of slope that you observe that you think is interesting. 2) Type the answers to the following questions regarding your picture: Do you think that your slope is positive, negative, zero, or undefined? Do you think that your slope is less than, equal to, or greater than one? Why or why not? What estimation would you give for the slope in your picture? How would making the slope undefined or zero or changing the slope from positive to negative or negative to positive affect the functionality/usability of your pictured item? Rise over Run is not typically used as a way to measure slope in "Real World" situations, so what units do you think are used to measure slope in your picture? TO RECEIVE FULL CREDIT FOR YOUR POST, PLEASE MAKE SURE THAT YOUR EXAMPLE IS DIFFERENT FROM THOSE OF YOUR CLASSMATES. NO TWO EXAMPLES SHOULD BE THE SAME! en-us 2016-12-02 16:11:26 UTC 2026-03-20 23:37:12 UTC hello@padlet.com csmith160 https://padlet.com/csmith160/5a38yg8aeayp/wish/141435532 The slope of this staircase is positive.  Since a person needs to walk up a staircase if they want to go the second floor, then the slope of it should be positive because lines with a positive slope go up from left to right.  The slope of this staircase is most likely equal to or slightly less than 1 to make it fairly easy to walk up the stairs.  If the slope is increased, then it will be harder to walk up and if the slope is decreased, it will be easier to walk up. If the slope is undefined, then the staircase is vertical and cannot be used and if the slope is zero, then the staircase is horizontal and not helpful for getting up to the second floor. The designers and architects of the staircase most likely determined what the slope of the staircase needed to be by taking measurements in feet and inches and at the very least considered distances and heights.]]> 2016-12-02 16:43:14 UTC https://padlet.com/csmith160/5a38yg8aeayp/wish/141435532 gdigangi2020 https://padlet.com/csmith160/5a38yg8aeayp/wish/142274446 The slope of this mountain is positive and negative at the beginning. The mountain is generally going up at a constant steep rate. My slope is greater than when the mountain is ascending, and less then one when it is going down. Starting at the bottom of the mountain it rises. When the mountain reaches its peak starts to descend fast. As the mountain starts to go down it falls at a constant rate. The mountain would be measured in miles. This mountain would be an extremely steep slope.]]> 2016-12-07 13:43:56 UTC https://padlet.com/csmith160/5a38yg8aeayp/wish/142274446 ckauffman2020 https://padlet.com/csmith160/5a38yg8aeayp/wish/142274492 The slope of a rainbow is positive and negative. It goes upwards, and then goes downwards. The slope would probably be more than one because a rainbow does not stay in one space, it goes in 2 different directions. If the slope changed, it would become a bigger rainbow since there is no limit to the physics of light and color. My slope estimation would be like 2/3 and goes to +1/+1 as it reaches the sky, then slowly goes back to 2/3 until it hits the ground. However, you would probably have to measure these areas in miles or by the visible eye since you can't actually touch a rainbow.

^ goes up and slows, then goes down quickly same as the speed it goes up]]> 2016-12-07 13:44:07 UTC https://padlet.com/csmith160/5a38yg8aeayp/wish/142274492 sfranklin2020 https://padlet.com/csmith160/5a38yg8aeayp/wish/142274575 The slope of a Basketball hoop is undefined rather than zero because it's constant rate is rising straight up. It is greater than one because it h'has no run. My slope is greater than because it rises only. The slope is (0,0) (0,10) and undefined.

The slope is about negative 1 because it is not that steep , if it were steeper the winch would have to be bigger and stronger to pull the corvette up.

The slope of the ramp is negative if you are at the top going down.
I think the ramp is less then one so people are able to go up it.

I would estimate that the slope of the ramp is 1/3 
I think this because it is fairly low to the ground and as not that long. If the slope was 0 it would be ineffective because no one could use the ramp to go up.]]> 2016-12-07 13:47:20 UTC https://padlet.com/csmith160/5a38yg8aeayp/wish/142275356 ctonelli2020 https://padlet.com/csmith160/5a38yg8aeayp/wish/142275726 The slope of a hill could be positive and negative.

The reason for this would because the line he is going down is downhill. So if you were to graph that same line, then the slope would be negative. My slope is going to be less than one since it is negative. The estimation I would give for my slope is about -5/2 because it's not the steepest hill, but also not the straightest. Making the slope undefined or zero could really change everything because if it's zero, then it would a straight line so the kid riding the car wouldn't be able to ride down it. Or if it was undefined, then it would be too steep and just a straight line going down. The unit used in my measurement would be meters because the hill that he is going down is a good amount of track, so meters would cover it up.]]> 2016-12-07 13:48:51 UTC https://padlet.com/csmith160/5a38yg8aeayp/wish/142275760 nferrucci2020 https://padlet.com/csmith160/5a38yg8aeayp/wish/142276071 The tower go vertical, which means it goes straight up.

This depends on where you start from. If you start at the blade and go up the shaft it arc's going up which would make it positive. If you start at the shaft and go down to the blade it arc's down and it makes it negative. I think it is greater then one because the stick is made to make your shot harder, the stick has different flex points on it so that means it is not the same all the way down. The slope of the stick is (0,0) and (5,10). The rise over run indicates that this equals 1/2. If it was undefined the stick would be perfectly straight.
