Question

help please!
What is the slope of a line perpendicular to a line that contains the points (-3, 8) and (-3, -6)

Answer 1

That line is not a funtion. I you compute the slope of the line, you have the following issue:
\[m=\frac{ 8--6 }{ -3--3 }\]
Which turns out to be:
\[\frac{ 14 }{ 0 }=\infty \]
You can't have a slope of infinity.

Answer 2

Unless.....it's a vertical line. GASP!

Answer 3

So, a line that is perpendicular to a line that has a slope of infinity has a slope of 0. DUH DUH DUH! (que scary music).

Answer 4

k, lol thanks can you help me with a few more??

Answer 5

Exactly...the two points contain the same x value meaning that it is a vertical line x=-3 therefore any horizontal line will be perpendicular to it. And a horizontal line has a slope of 0.

Answer 6

so whats the answer?
