Question

What is the slope of a line parallel to the line with equations y = -3? What is the slope of a line perpendicular to the line with equations y = -3.? Show work/explain answer accurately and correctly. Medal will be rewarded for your patronage! :D

Answer 1

infinity and zero

Answer 2

infinity my foot

Answer 3

\(y=-3\) is a horizontal line
the slope of a horizontal line is zero \(0\)
so any parallel line will also have slope \(0\)
a perpendicular line is vertical
a vertical line does not have a slope
or you could say "the slope is undefined"
