Need help rearranging formula.

I need help rearranging this formula. I'm doing Atomic Physics dealing with charge to mass ratio. I'm in Grade 12 Physics. Here's the formula:

(slope)= √(m/e)

I want to rearrange it so I get an equation that equals (e/m).
If you could show me how to do it that would be great

Starting with:

slope = sqrt(m/e)

Square both sides:

slope^2 = m/e

Take the inverse of both sides:

1/(slope^2) = e/m

Hope this helps!
