-$( 8 , - 1 )$ and $( 10 , - 7 )$
A) $m = 3$
B) $m = - 3$
C) $m = - \frac { 1 } { 3 }$
D) $m = \frac { 1 } { 3 }$

Question

Quizplus · Accepted Answer

The slope $m$ of a line passing through two points $(x_1, y_1)$ and $(x_2, y_2)$ is given by $m = \frac{y_2 - y_1}{x_2 - x_1}$. Substituting the given points, $m = \frac{-7 - (-1)}{10 - 8} = \frac{-6}{2} = -3$.
