Adding 15 to both sides. In order to get it to the opposite side of the equal sign, you must do its opposite. You can't add 8x to both sides, because the opposite of positive 8x is negative 8x and that's not what they're asking. The opposite of negative 15 is positive 15, so it works. Opposite of positive 3 is negative three, and they're wanting a positive, so it will not work. Adding 2x wouldn't work, because it's already positive..

All points on the blue curve f(x) are shifted up 4 units to get corresponding points on the red curve g(x). For example, the point (0,-3) moves up 4 units to (0,1).
g(x) = f(x)+k
g(x) = f(x)+4
