quiz review

1. find the slope of the graph.

process:

• pick 2 points.
• draw a triangle, create a table, or use the slope formula to find the slope.

m = ______________

Explanation:

Step1: Select two points

Let's choose the points (-10, 4) and (10, -8).

Step2: Apply slope formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Here, $x_1=-10,y_1 = 4,x_2=10,y_2=-8$. So $m=\frac{-8 - 4}{10-(-10)}$.

Step3: Simplify the expression

$m=\frac{-12}{20}=-\frac{3}{5}$.

Answer:

$-\frac{3}{5}$
