We shade a region because an inequality has a range of answers, not just a single boundary value. The shaded region represents all the ordered pairs (x, y) that satisfy the inequality.
Conditions: The relation being graphed is an inequality.; The graph is in a two-dimensional coordinate system.

The region above y=−4 is shaded because the inequality y>−4 requires the y-coordinate to be greater than -4. On a standard coordinate plane, larger y-values are located above the horizontal line y=−4.
Conditions: The inequality restricts y.; The boundary is a horizontal line y=−4.

To graph y>x−2, first identify the slope (m=1) and y-intercept (b=−2) from the slope-intercept form. Plot the y-intercept and use the slope to plot additional points.
Conditions: The inequality is in two variables (x and y).; The inequality is strict (>).
