which equation is equivalent to y - 6 = -12(x + 4)?

y = -6x - 48
y = 6x - 48
y = -12x - 42
y = -12x - 54

Please explain! Thanks!

What do you think the answer is? Expand the brackets and rearrange.

Honestly, I'm not sure on how to solve these. I missed the class and cant get a recording or anything.

y−6=−12(x+4)
Step 1: Add 6 to both sides.
y−6+6=−12x−48+6
y=−12x−42
Answer:
y=−12x−42

anonymous · Answer

No problem, I'll try and explain.$$y-6=-12(x+4)$$Expand the brackets$$y-6=-12*x-12*4$$Add 6 to both sides$$y=-12x-48+6$$$$y=-12x-42$$
So the answer is C.
