# How do you find the slope and intercept of  f(x)=-4x-8?

Jan 26, 2016

Given any linear function $y = \textcolor{red}{m} x + \textcolor{b l u e}{b}$
$\textcolor{red}{m} = \text{slope" and color(blue)b = "intercept}$
Thus color (red)m = -4; color(blue)b = -8 graph{-4*x -8 [-3.82, -0.401, -4.32, 4.94]}
