What's equivalent to y-1=-5(x-4). A, y=-5x-19. B, y=-5x+19 C, y=-5x-21 D, y=-5+21

it must be y=-5x+21

Step-by-step explanation:

lets type the equation in front of us and make it simple so we can deal with it

y-1=-5(x-4)

first thing you need to do is to remove those brackets by multiplying whats in the bracket by -5 like this

y-1=-5x+20             -5*x=-5,,  -5*-4=20 (note: when you multiply negative with

                                                               negative result is positive)

then add each side by 1 so it will be

y=-5x+21

(x, y)→(x − 8, y − 7)
