The following coordinate plane shows three of the vertices of a rectangle. On an 8 by 8 coordinate grid, T is plotted 1 unit right and 4 units up from the origin. P is plotted 6 units right and 2 units up from the origin. Z is plotted 3 units right and 5 units up from the origin. What are the coordinates of Point Z? ( ) What are the coordinates of Point P? ( ) Which point has coordinates (1,4) ? In order to create a rectangle using these points as three of the vertices, what coordinates should be used for the fourth vertex? ( )
