Absolute value inequalities

In order to graph an absolute value inequality one must use the formula y=a|x-h|+k. The point (h,k) is your vertex. Point "a" determines if your graph moves up or down. If Point "a" is negative the graph will move down, if the point is positive the graph will shift upwards.Point k determines whether your grph will shift left or right. If point k is negative the graph will shift to the right and if k is positive the graph will move left.
