Answer
Slope =

x-intercept =

y-intercept = -4
Explanation
Remember that the equation of a line in general form is:

where


Notice that to express our equation,
, in general form, we just need to subtract 12 from both sides of the equation:



Now can infer that
,
, and
. So let's replace the values in our formulas:







To find the x-intercept, we just need to replace
with zero in our general or original equation and solve for
:
