Hi there. I'm tryin to find a point, lets call it C. I'm working on a Rē. What I know is that the point belongs to the line L: $\displaystyle y=\displaystyle\frac{x}{2}+\displaystyle\frac{1}{2 }$ And that the distance to the point B(1,1), that belongs to L is $\displaystyle \sqrt[ ]{20}$.

How can I find it? I know there are two points, cause of the distance over the line.
