Open the “Secant” interactive figure, which is available in the Video & Resource Library of MyLab Math (under Interactive Figures) or at bit.ly/3raFUGB.

(a) Move Point A to (−2, −1) and Point B to (−1, 3). What is the slope of the secant line?

(b) Grab Point B and move it toward Point A. As Point B approaches Point A (but remains to the right of Point A), to the nearest integer, what does the value of the slope of the secant line approach?
