## Homework Statement

I've never seen such a problem before: Find the two straight lines that are perpendicular to [tex]y=0.25x[/tex] and tanget to the curve [tex]f(x)=1/x[/tex]

## Homework Equations

[tex]y=0.25x[/tex] ; [tex]f(x)=1/x[/tex]

## The Attempt at a Solution

Using the power rule, I found the derivatives of: [tex]f(x)=-x^{-2}[/tex] and [tex]y=0.25[/tex]

But I am not sure what I do now? Do I find the slope of the equations? Do I equate y=f(x)?
