What is the slope of a line that is perpendicular to the line y = 1?

1 answer:

3 0

The line Y = 1 is a horizontal line; its slope is zero.

A line perpendicular to Y = 1 is a vertical line.
Its slope is undefined.
(This does NOT mean that it's infinite, or anything else.
The slope of a vertical line is undefined. It doesn't have
a name or a symbol. It's nothing.)

Answer: y=-2x + 3

Step-by-step explanation:

(0,3) and (2,-1)

3-(-1)= 4

0-2= -2

4/-2= -2 so the slope is -2 and we already know the y intercept is 3 because that is when x is 0.
