Question

find the slope of the line. -4/5 4/5 -5/4 5/4

Explanation:

Step1: Recall slope formula

The slope formula for a line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is $m=\frac{y_2 - y_1}{x_2 - x_1}$. If we assume the line passes through points such that for a decrease of 4 units in the y - direction there is an increase of 5 units in the x - direction (visually from the graph), then $y_2-y_1=- 4$ and $x_2 - x_1 = 5$.

Step2: Calculate the slope

$m=\frac{-4}{5}$

Answer:

A. $-\frac{4}{5}$
