We can determine if the graph is the solution to the inequality by plugging in values for x and y by using specific coordinates from the graph and plugging them into the inequality. We plugged in the coordinates (-1,3) from the graph and found that it was the solution to the inequality. It was on the shaded region of the graph and was not on the dotted line. The other coordinate (2,-2) was in the unshaded region which means that those coordinates are not a solution to the inequality.

in the coordinate plane there is a dotted line so we have to find a(n) solution that isnt equal to y. We used the coordinates (-1,3) and thats the solution to the inequality.

plug in value for x and y to find the answer to the equation
to see if it works. Pick a coordinate above the dotted line to plug into x and y. We plugged in (-1,3) from the graph and found that it was the solution to the inequality.

By pluggin in values for x and y by using coordinates from the graph and plugging them into the inequality

On the coordinate plane we have a dotted line so we have to find a solution that is less than y. So you have to plug in the coordinates on the graph and test it out. After trying (-1,3) we found out that this graph is a solution to the inequality since the coordinate that worked is on the shaded side and the Other coordinate (2,-2) isn’t shaded in on the graph. Lastly since the > sign does not have a line under it the line on the graph will not be solid it will be dotted.

You plug in the value in for X and Y to find the answer of the inequality using the coordinates from your graft. You have to plug them in to the problem and see if the coordinates match what the problem is saying. Make sure the coordinates give you a true statement when they are plugged in.

You have to plug in the x and y values to find out if this graph will work.The equation is y>4x-5.5. The first coordinates were going to use is (-1,3).When we did that we got 3>(-9.5). The second coordinate we use was (2,-2). the final answer of this problem is -2>2.5. so that means these coordinates won't work for this equation.

Most of time when we have to plug in pairs (x,y) for a inequality there has to be this line that divides the graph and half of the graph has to be shaded in and mostly everything inside the shaded part can be a solution for your inequality but you can test it out your self buy plunging in some of the pairs on that shaded part but if you get lucky some of the pairs should be already plotted on the graph and you can plug those in to your problem to see if the graph is a solution to your problem

You pick a coordinate above the dotted line and plug in the x and y coordinates into the equation.

you can determine if the graph is a solution, by plugging in coordinates to the equation, and see if it works. the coordinates (-1,3) is a solution for the graph shown below.

you plug the x and y coordinates into the equation from above the dotted line.
y>4x-5.5 so if you plug in -1,

-2>4(2)-5.5

-2.8.0-5.5
-2<2.5
The graph is a solution to the inequality

You can check if the graph is a soloition by plugging in shaded coordinate and if it works they then graph is an awnser.

True, after we put the solution into a graph/chart, the solution set we were given turned out to Be true.
Y>4x-5.5
3>4(-1)-5.5
3> - 4-5.5
3>-9.5
3 is greater than negative 9.5

You have to apply the given coordinates (the X and Y value) from the graph, and solve the equation. If the equation is true, then the given coordinates are solutions.
Y > 4X - 5.5 (coordinates: X= -1 Y= 3)
3>4(-1)-5.5
3>-4-5.5
3> -9.5

you have to plug in the value for X and Y to find the asnwer to the inequality you just pick a coordinate from above the dotted line then plug it in to find the soulution then you plug it in and if the solution is less than Y in the solution for the warm up the solution becomes true
