Question

Help please I am confused inverse variation problem

Answer 1

y = 2

Explanation:

y = 6 ⇔ x= 3

y = ? ⇔ x = 9

y = 6*3/9

y = 2

Answer 2

y =2

Explanation:

Inverse variation is of the form

xy = k

3*6 = k

18 = k

xy = 18

Now when x = 9, find y

9*y = 18

Divide by 9

y = 18/9

y =2

When x =9, y =2
