3-55.

Lourdes has created the following challenge for you: She has given you three of the four points necessary to determine a rectangle on a graph. She wants you to find the points that “complete” each of the rectangles below, and then calculate the area of the rectangles formed in parts (a), (b), and (d).

1. $(–1, 3),$ $(–1, 2),$ $(9, 2)$

$(9, 3)$

1. $(3, 7),$ $(5, 7),$ $(5, –3)$

1. $(–5, –5),$ $(1, 4),$ $(4, 2)$

1. $(–52, 73),$ $(96, 73),$ $(96, 1483)$

Use the eTool below to help you determine the final points of the the rectangles.
