Slope, m

Parallel lines

Perpendicular lines

The equation of a line whose intercepts are a and b on the coordinate axes respectively

Three points

A (x_{1}, y_{1})

B (x_{2}, y_{2})

and

C (x_{3}, y_{3})

are collinear

\frac{c h a n g e i n y c o o r d i n a t e s}{c h a n g e i n x c o o r d i n a t e s}

m_{1} = m_{2}

m_{1} . m_{2} = - 1

\frac{x}{a} + \frac{y}{b} = 1
