Answer:
D(3, 3)
The slope of line AB is -2.
The slope of line CD is 1/2.
Explanation:
I chose point D (shown in the figure below) since it lies on the intersection of grid lines and is easy to read. The coordinates of point D are (3, 3).
Point A(-3, 3); point B(-1, -1)
slope of line AB:
The slope of line AB is -2.
Point C(1, 2); point D(3, 3)
slope of line CD:
The slope of line CD is 1/2.
