How do you graph y <x and x>5 on the axes below?

See below.

Explanation:

First plot the line y=xy=x. This will give you one of the boundary lines. Remember to use a dashed line as this is a less than inequality and not a less than or equal to inequality.

Plot the line x=5x=5. This will give you another boundary line. As before use a dashed line, because this is a greater than and not a greater than or equal to.

Test values on either side of each line to determine what region is shaded.

For y < xy<x, if x = 4x=4, y < xy<x below the line y=xy=x

For x>5x>5 , if x=6x=6, to right of line x=5x=5

To satisfy both conditions.

x > 5x>5 and y < xy<x

if x=6x=6 and y = 2y=2

This is the region below the line y=xy=x and to the right of the line x=5x=5. This is shown as the grey region on the graph.

This can seem a bit confusing. It is generally best practice in a case like this to plot the line of each inequality and determine the regions by examining the graph.
