# What is the slope and y-intercept of this line f(x)= -8x - 7?

The slope-intercept form of a linear equation is: $f \left(x\right) = \textcolor{red}{m} x + \textcolor{b l u e}{b}$
Where $\textcolor{red}{m}$ is the slope and $\textcolor{b l u e}{b}$ is the y-intercept value.
For this equation $f \left(x\right) = \textcolor{red}{- 8} x + \textcolor{b l u e}{- 7}$
The slope is $\textcolor{red}{m = - 8}$
The y-intercept is $\textcolor{b l u e}{b = - 7}$ or (0, $\textcolor{b l u e}{- 7}$)
