$y = 1 x + 4$ $y = color(red)(1)x + color(blue)(4)$

Or

$y = x + 4$ $y = x + color(blue)(4)$

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

The slope-intercept form of a linear equation is:

$y = m x + b$ $y = color(red)(m)x + color(blue)(b)$

Where $m$ $color(red)(m)$ is the slope and $b$ $color(blue)(b)$ is the y-intercept value.

Substituting the values from the problem results in:

$y = 1 x + 4$ $y = color(red)(1)x + color(blue)(4)$
