I need help pleaseee asap

Step-by-step explanation:

there is no big "trick" involved.

you just need to do the multiplication and then move the terms into the right spot, so that the x-, y- and constant terms are in the same place as the generic Ax + By = C

y + 5 = 4(x + 1)

y + 5 = 4x + 4

-4x + y = -1

or (after multiplying both sides by -1)

4x - y = 1

yes, B = 1 (or -1), so you could write 1y (or -1y) instead of only y (or -y).

but nobody does that.

the answer is. -82562234434584
