The general absolute value equation is in the form y = a|x-h|+k where (h,k) is the vertex. If you're given the vertex, you can immediately find h and k (and plug them in). To find the value of 'a', you would then plug in (x,y) (the given point, that's not the vertex, that lies on the absolute value graph) and solve for it.
