# How do you write the slope-intercept form for the equation of a line with slope m=1 and y -intercept (0, -9)?

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 from the problem gives:

$y = \textcolor{red}{1} x + \textcolor{b l u e}{- 9}$

$y = \textcolor{red}{1} x - \textcolor{b l u e}{9}$

Or

$y = x - \textcolor{b l u e}{9}$
