1) Draw a straight line through the points. Then, draw two right triangles above the graphed line: one between point A and point B, and another between point B and point C.
2) Determine the rise for both triangles. Label each triangle with “rise =" and the correct
numerical distance and direction.
3) Determine the run for both triangles. Label each triangle with “run =" and the correct
numerical distance and direction.
4) a. Is the function increasing or decreasing?
b. How do you know?
rise
5) Find the slope as a unit rate of the triangle between points A and B using m=
run
