Question

What is the slope of the line that passes through the points (-4,0) and (-4, -10)?

Write your answer in simplest form.

Answer 1

the slope is undefined

Explanation:

slope = y2 - y1

___________

x2 - x1

slope = (-10-0) / {-4 - (-4 ) }

slope = -10 / (-4 + 4)

slope = -10 / 0

slope = undefined

note - Any number divided by zero is undefined
