(y2-y1) divided by (x2-x1) is the formula to find the slope of two coordinates.
Distance formula: look at attached image because it is hard to understand in words ;)
Midpoint formula: (x1+x2) divided by 2, (y1-y2) divided by two - look at attached image
Pythagorean Theorem: a squared plus b squared = c squared - look at attached image
Slope Formula: y=mx+b
