B (3,5)
7
6

1
C (4,5)
Plot the points above in alphabetical order. Then, identify the fourth point needed to create a rectangle.
Write the coordinates of the fourth point D of the rectangle.

Answer 1

Plot the points in order: A(3,1), B(3,5), C(4,5).

To complete the rectangle (sides parallel to the axes), the missing vertex has the x-coordinate of C and the y-coordinate of A:
D = (4, 1).

So D(4,1).
