By smenks13:

I think the concept of point slope form might be better reinforced if the solution is shown in that format, (y - y1) = m(x - x1). I think I realize why you did it this way, because slopes of -1, 0, and 1 are problematic as they wouldn't be shown in front of the parentheses, but we may be better off data-ensuring that those don't come up. The only reason I say that is users can just bypass the whole concept if they figure out the slope and plug in one of the points as it stands. I'll think more about this and circle back with you.
