Answer
C, y=-3x-6
Work Step by Step
The equation y+12=-3(x-2) is written in point-slope form, and to rewrite it in slope-intercept form we being by applying the distributive property (which says that a(b+c)=ab+ac) to the right side of the equation, so
y+12=-3x+6
Finally, we must solve for y. To do this, we simply subtract 12 from both sides to get
y=-3x-6
