Question

The variable y varies directly with x . If x=2 and y = −7, find y when x = −6.

Answer 1

Explanation:

`(2)/( - 6) = ( - 7)/(y) \\ y = (( - 6) * (- 7))/(2) \\ y = (42)/(2) \\ \boxed{y = 21}`

21 is the right answer.

Answer 2

Explanation:

X=2

Y=-7

Then if x is -6 u have to find what times 2 is -6 Which is -3.

so -7 x -3 is 21. Y is 21
