| Straight line graphs can be written in the form: | y = mx + c or ax+by+c = 0 |
| To find the gradient with two points (x, y) and (x’, y’) | y’-y/x’-x |
| Equation given point and gradient | y - y’ = m(x-x’) |
| Mid point of (x,y) and (x’,y’) | (x+x’/2, y=y’/2) |
| Distance between (x,y) and (x’,y’) | square root of (x’-x)^2 + (y’-y)^2 |
| Equation of a circle | (x-a)^2 + (y-b)^2 = r^2 |
