Question

find the slope of ad. a (-4,1) b(-1,3) c(3,1) d(0,-1) a. -2 b. -1/2 c. -1 d. 3/2

Explanation:

Step1: Recall slope formula

The slope formula between two points $(x_1,y_1)$ and $(x_2,y_2)$ is $m=\frac{y_2 - y_1}{x_2 - x_1}$.

Step2: Identify points A and D

Point A has coordinates $(-4,1)$ so $x_1=-4,y_1 = 1$. Point D has coordinates $(0,-1)$ so $x_2 = 0,y_2=-1$.

Step3: Substitute values into formula

$m=\frac{-1 - 1}{0-(-4)}=\frac{-2}{4}=-\frac{1}{2}$.

Answer:

B. -1/2
