8-8.

Set up a graph and plot four points that form the vertices (corners) of a rectangle. Then write the coordinates of the four points and find the length of each pair of sides.

When drawing your graph, make sure that the quadrilateral has four right angles. Otherwise, it is not a rectangle.

Coordinates are written in the form (*x, y*). The *x*-axis is horizontal, and the *y*-axis is vertical.
