How do you show an inequality on a graph?

Plot a straight line of the same equation. If the inequality is strict ( < or > but not equal to) then draw the line as a dashed line. Otherwise draw a solid line. You then need to shade the correct region for which the inequality is true. So pick a point on one side of the line and put the x and y values of that point into the equation... if the inequality is still true for those values, shade the region that contains your point. If not, shade the other side of the line!
