Question

What is the equation of the line that passes through the point (3,-7) and has an undefined slope

Answer 1

x = 3

Explanation:

x = 3

slope = (y - y') / (x - x')

since x-x'=0, slope is undefined

Answer 2

×=3

Explanation:

undefined slope equations always start with x=

you only have to know the x intercept, so it's just 3.

now piece them together: x= 3
