324 * Equation of a line with slope m and y-intercept b:
342 // slope and y-intercept of the focus-perimeter line
343 double slope, yintcpt;
393 // slope and y-intercept of the focus-perimeter line
394 slope = (Y - focusY) / (X - focusX);
395 yintcpt = Y - (slope * X);
399 A = (slope * slope) + 1;
400 B = precalc3 + (-2 * slope * (centerY - yintcpt));
410 solutionY = (slope * solutionX) + yintcpt;
