Slope: (-3)
y-intercept: -1/2

Explanation:

The easiest way to handle this question is to convert
the given equation: -12x-4y=2
into "slope-intercept" form:
color(white)("XXX")y=color(green)(m)x+color(blue)(b) with slope color(green)(m) and y-intercept color(blue)(b)

-12x-4y=2
color(white)("XXX")rarr -4y=12x+2

color(white)("XXX")rarr y=color(green)(-3)xcolor(blue)(-1/2)
which is in slope-intercept form with slope color(green)(""(-3)) and y-intercept color(blue)(""(-1/2))

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If the x-intercept is also required,
it can be found by setting y=0 in the original equation
and solving for x
color(white)("XXX")-12x-4(0)=2

color(white)("XXX")rarr x=-1/6
