If y = - 12 when x = 9

find y when x = - 4

This is a fraction. So it's y over x. So - 12 over 9 equals y over - 4. After you put those in fractions, you cross multiply. So - 12 (-4) is 48, and 9y. Then you set them equal to each other, so 48=9y. You divide 9 on both sides and your answer should be y=5.3
