Answer:
y=7x, y=-5x, y=24x, y=-2x
Explanation:
7. each of the Xs multiplied by 7 is the Y, so y=7x
8. the function is inverse, so we can assume that x is negative, and after we multiply the x by -1, we find that the rule is multiply by 5, so y=-5x
9. looking again at the pattern, we can find that x * 24 is the y, so y=24x
10. again, the function is inverse so x is negative, and the pattern is multiplying by 2, so y=-2x
