How do you graph y= 12+2x using intercepts?

Try this:

Explanation:

We start from the $x - \text{intercept}$ by setting $y = 0$, so we get:
$0 = 12 + 2 x$
$x = - \frac{12}{2} = - 6$
so:
$x -$intercept at: $\left(- 6 , 0\right)$

Then we find the $y - \text{intercept}$ by setting $x = 0$, so we get:
$y = 12$
so:
$y -$intercept at: $\left(0 , 12\right)$

Graphically:
