# How do you write 0=x+5 in slope intercept form?

Unfortunately, it cannot be written in Slope-Intercept Form since this is a vertical line, which means that its slope is undefined. In order to use Slope-Intercept Form, we must have its slope and $y$-intercept. Instead, you can write it in General Form $A x + B y = C$ as
$x = - 5$
