Question

what is the slope of the line in the graph below?

Explanation:

Step1: Select two points on the line

Let's take two points, say (-5, 2) and (5, - 2).

Step2: Use the slope - formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Here, $x_1=-5,y_1 = 2,x_2 = 5,y_2=-2$. Then $m=\frac{-2 - 2}{5-(-5)}=\frac{-4}{10}=-\frac{2}{5}$.

Answer:

$-\frac{2}{5}$
