B since you're talking about perpendicular
Wish I could help. :( But I'm not sure.
She didn’t multiply -1/4 by 12 in order to get -1/4x + 3 = -1
which would change her answer, because then you have to subtract 3 from -1 and get -4. Then divide -1/4 & get 16. It changed to positive because of the division & multiplication rule with two negative numbers.
Hope this helps.
