ALGEBRA If y varies directly with x, write an equation for the direct variation. Then find each value. 9. If y = –5 when x = 2, find y when x = 8.

10. Find y when x = 1, if y = 3 when x = 2.

11. If y = –7 when x = –21, what is the value of x when y = 9?

12. Find x when y = 18, if y = 5 when x = 4.
