Open the “Slope” interactive figure, which is available in the Video & Resource Library of MyLab Math (under Interactive Figures) or at bit.ly/3raFUGB.
(a) Be sure the “Show Slope” box is not checked. Grab point B and move it to the point with coordinates (3, 5). What is the value of the “Rise”? What is the value of the “Run”? Select the “Show Slope” box. What is the value of the slope?
(b) Grab point B and move it to the point with coordinates (4, −3). What is the value of the slope?
(c) What is the value of the slope if the line is horizontal?
(d) Which of the following lines have a slope that is negative? Select all that apply.
(i) The line through (1, 3) and (4, 4)
(ii) The line through (1, 3) and (4, 2)
(iii) The line through (1, 3) and (1, 6)
(iv) The line through (1, 3) and (−1, 5)
(v) The line through (1, 3) and (−1, 0)
(e) If the value of the “run” is positive and remains unchanged, then as the value of the “rise” decreases, the slope of the line______.
(i) Increases

(ii) Decreases

(iii) Remains unchanged

(iv) Cannot be determined
