The variables x and y vary inversely. Use the given values to write an equation relating x and y. Then find y when x = 2.

Question

1. x = -1, y = 29
2. x = 8, y = 11

Answer 1

yx = c is an inverse relation between y and x. In #1 c = -29 and in #2 c = 88

The equation for y is y = c/x

In #1 y = -29/x x = 2 implies y = -29/2

I'll leave #2 for you.
