Question

What is the slope of a line perpendicular to A (-4, 2) and B(4, 2)?

A (-4, 2) and B(4, 2) have a slope of 0, so how can I find the slope to the perpendicular line?

Answer 1

the slope of a line of A (-4, 2) and B(4, 2) is \[2-2 \over 4+4\] = 0

so have a line perpendicular to it has to be opp and negative of what ever the slope is.

so the slope perpendicular to A (-4, 2) and B(4,2) would also be 0.

Answer 2

Thank you!! :)

Answer 3

no problem ;)

Answer 4

Wouldn't the slope be
\[-\frac{1}{0}=-\infty\]

Answer 5

There was no slope.
