Best ResponseYou've already chosen the best response.0insert your 3 points for (x,y) into the abstract formula, you get three equations for a,b and c. Solve them and you have the solution.

Best ResponseYou've already chosen the best response.0The ones I've done in the past end up factoring out so that a, b, or c shows easily and I've worked this one 3 different ways and I'm still having problems coming up with a value for any of them. I found examples that had 0 as a y coordinate but not the x.
