Question

What is the slope of the line that passes through the points (-9,8) and

(-21, 10)? Write your answer in simplest form.

Answer 1

The slope is -1/6

Explanation:

We simply use the slope formula here

Mathematically, we have this as;

m = (y2-y1)/(x2-x1)

thus;

m = (10-8)/(-21 + 9) = 2/-12 = -1/6
