What's the correct graph

[From: ] [author: ] [Date: 11-07-01] [Hit: ]
-I think it is picture 2 BUT, the right hand line should go through x = 5 NOT x = 6.......
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.

2 < x < 5 and y > 3
