Question

Find an equation of the line passing through each of the following pairs of points. d (0, 7), (0, −8)

Answer 1

x=0

Explanation:

The slope is 0 so the line is technically undefined.

m = -8-7/0-0

m = -15/0

m = 0

x=0

Answer 2

m = undef

Explanation:

Slope Formula:
`m=(y_2-y_1)/(x_2-x_1)`

Simply plug in the 2 coordinates into the slope formula to find slope m:

`m=(-8-7)/(0-0)`

`m=(-15)/(0)`

m = undef
