Question

Teh slope between two points is calculated by finding the change in y-values and dividing by the change in x-values. for example, the slope between the points (7,-15) and (-8,22) can be computed as follows. answer key

Answer 1

Hi there!

The change of y-values is
- 15 - 22 = - 37
The change of x-values is
7 - - 8 = 7 + 8 = 15

Therefore, the slope of this line is
$\frac{ - 37}{15} = - 2 \frac{7}{15}$
