Find the slope of the line perpendicular to the line with the given
information:
y = -7

Answer 1

Undefined

Explanation:

`y=-7` has a slope of
`0`, since it is a horizontal line. The only types of lines that are perpendicular to horizontal lines are vertical lines, which are usually in the form
`x=a` (where
`a` is any real number). Vertical lines have an undefined slope, so the answer is undefined. Hope this helps!
