Question

What is the slope of a line perpendicular to the line whose equation is x+y=9

Fully simplify your answer.

Answer 1

1/2x

Explanation:

To find perpendicular slope, you have to find the inverse of the x. First, though, you have to get y by itself. To do this, subtract x, moving it to the other side of the equation. You end up with y=-x+9. After that, all you need to do is find the opposite x, which is 1/2x. Since it's only asking for a slope, that's your answer.
