Key Equations

slope-intercept form of a line	$f (x) = m x + b f (x) = m x + b$
slope	$m = \frac{change in output (rise)}{change in input (run)} = \frac{Δ y}{Δ x} = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} m = \frac{change in output (rise)}{change in input (run)} = \frac{Δ y}{Δ x} = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$
point-slope form of a line	$y - y_{1} = m (x - x_{1}) y - y_{1} = m (x - x_{1})$
