Question

1. find the slope of the line.

Explanation:

Step1: Select two points on the line

Let's take the points $(0,0)$ and $(-4, 4)$.

Step2: Use slope - formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Here, $x_1 = 0,y_1 = 0,x_2=-4,y_2 = 4$. So $m=\frac{4 - 0}{-4-0}$.

Step3: Calculate the slope

$m=\frac{4}{-4}=- 1$.

Answer:

$-1$
