# How do you write an equation of a line with slope 1 and y-intercept 4?

Jan 29, 2017

$y = \textcolor{red}{1} x + \textcolor{b l u e}{4}$

Or

$y = x + \textcolor{b l u e}{4}$

#### Explanation:

We can use the slope intercept formula to find the equation.

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 values from the problem results in:

$y = \textcolor{red}{1} x + \textcolor{b l u e}{4}$
