So in order to plot , we need to plot the equation first
Graph of
Now plug in a test point (0,0) into the inequality
Plug in and
Evaluate and simplify
Since the inequality is true, this means that we shade the entire region that contains the point (0,0). So this means that we shade everything below the line . Note: Since the inequality is a "less than" sign, this means that the line should be a dotted line.
