For an x-inequality, shade to the right if x is greater than the boundary value (x>cx > c or x≥cx \ge c), and shade to the left if x is less than the boundary value (x<cx < c or x≤cx \le c).

Conditions: The inequality restricts x.; The boundary is a vertical line x=cx = c.

To graph y>x−2y > x - 2, first identify the slope (m=1m = 1) and y-intercept (b=−2b = -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 (>).
