Answer
Slope = 3
Y-intercept = 12
X-intercept = -4
Work Step by Step
Because the number preceding x in the formula is 3, we know that the slope of the line is 3.
To find the y-intercept, we set x = 0.
$y = 3(0) + 12$
$y=12$
To find the x-intercept, we set y = 0.
$ (0) = 3x + 12$
Then subtract 12 from both sides.
$ -12 = 3x $
And divide by 3.
$ -4 = x $
