y = mx + b , point slope formula, y2 - y1 over x2 - x1

[php]

I've been having a tutor for the past week or two. I had no background in geometry nor algebra (I've done it, just blew it off). I'm trying to understand these three things more straightly. Because every time the tutor comes to my house, he has to refresh my memory with the "y = mx + b", "y2 - y2 (over) x2 - x1", and the "point slope formula. My question is, is there a way that this can be permanently injected into my brain? I'll even go for a song. I just need to get this down, because my tutor gets pissed when I go brain dead after he explained the exact same thing to me a day earlier.

Thanks.
