Homework Equations
y=mx +b
The Attempt at a Solution
Well, I thought this was going to be an easy one but I'm running out of creativity. I would still like to solve this one so it would be nice if I could get a small shove in the right direction.
I starting thinking about the properties of a unit circle in order to locate a point on the circle. I was then planning on taking the derivative at that point to find the slope of the line and construct the equation from there.
The problem with that approach is that I am not sure how to figure out what point that is. I am open to trying another approach as well.
