Question

Line AB contains points A (−3, 5) and B (−3, 3). Line AB has a slope that is

Answer 1

Step-by-step explanation:

A = (-3, 5) B = (-3, 3)

x1 = -3 y1 = 5

x2 = -3 y2 = 3

slope of the line

$= \frac{y2 - y1}{x2 - x1} \\ = \frac{3 - 5}{ - 3 - ( - 3)} \\ = \frac{3 - 5}{ - 3 + 3} \\ = \frac{ - 2}{0} \\ = \infty$

the slope of line AB is infinite

it shows the line is perpendicular to x axis

hope you get your answer
