15. Three of the four vertices of a parallelogram have the following coordinates.
(4, 3) (5, –1) (8, 3)
Plot these points on the coordinate grid below.
Then, plot all three possible points for the fourth vertex.
Write down the coordinates of these three points. [4]
The three possible points for the fourth vertex are
(……… , ………) (……… , ………) (……… , ………)

| Three correct possible points for the 4th vertex plotted (red crosses below) AND correct coordinates given. (7, 7) (9, -1) (1, –1)  The red crosses are the circled crosses (red in the original). | B3 | Answer lines take precedence. For P1 B3 only 6 points should be plotted on grid. Award B2 for one of the following:
