Question

Find the slope of the line that passes through (2,21) and (84, -30)

Answer 1

-51/82.

Step-by-step explanation:

Given two points (x1,y1)=(2,21) and (x2,y2)=(84,-30), we find the slope using the formula below:

`m=(y_2-y_1)/(x_2-x_1)`

Substitute the given points:

`\begin{gathered} m=(-30-21)/(84-2) \\ m=-(51)/(82) \end{gathered}`

The slope of the line that passes through the given points is -51/82.
