Question

Find the slope of the line that passes through points (9,8) and (4,-2).

Answer 1

You can find the slope of the two points with the following formula:

$m=\frac{y2-y1}{x2-x1}$

Substitute the corresponding values into the equation.

$m=\frac{-2-8}{4-9}$

$m=\frac{-10}{-5}$

$m=2$

The slope of the line is 2.
