Question

Write an equation of the line with the given slope and y-intercept.

Undefined slope; (-8, 5)

A. x = -8

B. 5x - 8y = 0

C. y = 5

D. -8x + 5y = 0

Answer 1

A. x = -8

Explanation:

It can't be B because the slope of this equation is 5/8.

It can't be C because this equation slope is 0, not undefined.

It can't be D because the slope of this equation is 8/5

I say it is A because this is the only equation with an undefined slope!
