Answer:
Slope is Rise/Run or (-2/16) or - (1/8)
Explanation:
Slope is also known as the Rise/Run between two points on a line. The Rise it the change in y and the Run is the change in x that produces the change in y.
Take two points from lowest to highest x and calculate the Rise and Run:
(-7,4) to (9,2)
Rise = (2 - 4) = -2
Run = (9 - (-7)) = 16
Slope is Rise/Run or (-2/16) or - (1/8)
