Question

Find the slope of the line that passes through points (-1, -10) and (-1, -2)

Answer 1

Answer:

undefined

Step-by-step explanation:

$\boxed{slope = \frac{y1 - y2}{x1- x2} }$

☆ (x₁, y₁) is the 1st coordinate and (x₂, y₂) is the 2nd coordinate.

Slope of the line

$= \frac{ - 2 - ( - 10)}{ - 1 - ( - 1)}$

$= \frac{8}{0}$

(undefined)

Notice that the 2 points have the same x-coordinate of -1, which means that the line is a vertical line. Vertical lines have an undefined slope.
