Answer 2

@SolomonZelman plz help when u r done with the other question

Answer 3

graph them.

Answer 4

I did now what @SolomonZelman

Answer 5

What ?

Answer 6

I graphed the two inequatlities now how do I figure out hot to find the points on the graph @SolomonZelman

Answer 7

Why don't you just substitute the coordinates of the options for the answers?
The first one lists A, C, D, and K. The coordinates are as follows:
A: (-5,4)
C: (-2, 7)
D (-7, 1)
K (2, 3)

However after you graphed the two inequalities, it should be a very easy matter just to observe the points to test if they are in the solution area. The manner I am suggesting requires more work.

Answer 8

I graphed all the points but there are only two solutions which are coordinates H and J

Answer 9

This is the Graph @radar

Answer 10

The coordinates are labeled differently though

Answer 11

The graph does not appear, I get a message saying unable to launch. I checked those coordinates for points A, D, D, and K and they all fours are in the solutions area. However, if you notice the third choice has all those points also, plus point H. You will have to check that out by plugging the coordinates for H into either the two equations to test them or mark the point on your graph to see if it is in the solution area.

I have to go now, good luck with these.
