4x + y = -1
If your putting it in Slope Intercept Form then you will. . . .
4x + y = -1
Subtract y on both sides because it is the opposite of addition.
4x = -1 - y
Next, you'll add 1 on both sides because it is the opposite of subtraction.
4x + 1 = -y
Last you'll divide each side by a -1 because you y has to be a positive.
-4x - 1 = y
-Gives you thumbs up-
