Question

What is the slope of the line that

passes through these two points?
(-4, 6)
(-4,-2)
Remember. Slope is
a) 0
rise (y2-yı)
run (x2-x1)
c) undefined
b) 1/3
d) -3

Answer 1

undefined

Explanation:

( -4, 6) & (-4, -2)

To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(-2 - 6) / (-4 - (-4))

Simplify the parentheses.

= (-8) / (-4 + 4)

= (-8) / (0)

Simplify the fraction.

-8/0

= undefined

This slope is undefined because you cannot divide a number by 0. These points also fall on a vertical line, which has an undefined slope.

Hope this helps!
