Question

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

Undefined slope, (0.-1)
The equation of the line is?

Answer 1

x=0

Explanation:

Undefined slope is a vertical line:

Vertical lines are represented with x= something

Because the line passes through (0, -1) x=0

Answer 2

y = -1

Explanation:

Undefined slope means the line is vertical or of the form

x =

Since the point is (0,-1) the x value is 0

x = 0
