First of all you have to write down your line-equations for the wall and for the ray: (wall) y = m1 * x + b1. (ray) y = m2 * x + b2. Since we're searching for a point of intersection we need to put those equations together: m1 * x + b1 = m2 * x + b2. Well, there are a lot of unknown values. highland creek golf club reviews https://ptforthemind.com
