I have to graph and solve systems of linear inequalities in two variables..
Choose the correct solution.
x − 2 > 0
x < 5
y − 3 > 0

rearrange to give:
x > 2
x < 5
y > 3
then draw on the lines replacing the inequality signs with '=' and refer back to the direction of the inequality sign to shade in the right side.
The line y=3 is above the x axis as it is positive so you know it cannot be graphs 1 or 3.
You also know x is between 2 and 5 (it is bigger than 2 but less than 5) so the area in between the two lines must be shaded. Therefore it is not graph 4, it is graph 2.

I think it is picture 2 BUT, the right hand line should go through x = 5 NOT x = 6.
2 < x < 5 and y > 3

2 < x < 5 and y > 3
