Plot the following points:

a. -6,-1

b. 6,-7

The plot of point (-6,-1) would be at the coordinates (-6,-1) on a Cartesian plane. It would be a point located 6 units to the left of the origin (x-axis) and 1 unit down from the origin (y-axis).

The plot of point (6,-7) would be at the coordinates (6,-7) on a Cartesian plane. It would be a point located 6 units to the right of the origin (x-axis) and 7 units down from the origin (y-axis).
