Question

what is the slope of this line? (-1, 3) (-1, 1) 2 -2 0 undefined

Explanation:

Step1: Recall slope formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$, where $(x_1,y_1)$ and $(x_2,y_2)$ are two points on the line.

Step2: Identify two points

The two - points on the line are $(-1,1)$ and $(-1,3)$. Here $x_1=-1,y_1 = 1,x_2=-1,y_2 = 3$.

Step3: Substitute into formula

$m=\frac{3 - 1}{-1-(-1)}=\frac{2}{0}$.

Answer:

undefined
