(-3,-0.5) (-2.5, -3) (-2, -4.5) (-1.5, -5) (-1, -4.5) -0.5, -3) and (0, -0.5)

honest_denverco09 wrote:i still be stuck in part that how can i figure out the coordinates of the vertex in these seven points, will the vertex be the middle point ? If so, how can i find the vertex when the number of points that are given is the even numbers ?
