do you know how to solve it when it's equalities? like 2x  y = 7 5x  y = 2

Yea, I know how to solve for Y and X I'm just confused how to choose the points. And sorry for not putting them. (–2, –5) (–2, 5) (2, –5) (2, 5)

Here is a better graphich. The region between the two lines must have the answers for the system.

@wtoliver 2x – y > 7 5x – y > 2  Test each of the points. If (–2, –5) is a solution, then it has to satisfy both inequalities.

2x – y > 7 Test Point (2,5) 2(2)  (5) > 7 > ? 4 + 5 > 7 >? 1 > 7 > No So, the point (2,5) is not a solution. No need to test the second inequality because the point does not satisfy the first inequality.

Next, look at the second point (2,5). Note: y = 5 and x = 2. lst inequality to check 2x – y > 7 Point to test (2,5) Is 2(2)  5 > 7 Is 4  5 > 7 Is 9> 7 No. Go to next point to test and contine.
