# How do you write the slope intercept form of the equation given slope -1 and y intercept -1?

See a solution process below:

#### Explanation:

The slope-intercept form of a linear equation is: $y = \textcolor{red}{m} x + \textcolor{b l u e}{b}$

Where $\textcolor{red}{m}$ is the slope and $\textcolor{b l u e}{b}$ is the y-intercept value.

Substituting the slope and $y$-intercept given in the problem allows us to write the equation as:

$y = \textcolor{red}{- 1} x + \textcolor{b l u e}{- 1}$

$y = - x - \textcolor{b l u e}{1}$
