ax + by + c = 0

C is the y-intercept

M is the gradient

change in y

gradient = change in x

Distance between two points

Use Pythagoras

distance = (change in x) + (change in y)

Midpoint of a line

x1+x2 , y1+y2

Parallel and Perpendicular Lines

Parallel lines have the same gradient

Perpendicular gradients: gradient 1 ×gradient 2 =- 1

-1

gradient 1 = gradient 2
