Question

The variables x and y are related proportionally. When x = 8, y = 14. Find y when x = 16. When x = 16, y

Answer 1

y=28 because when you divide 16 and 8 it equals 2. So, multiply 14 and 2 to get 28.

Answer 2

y = kx

14 = k*8

k = 14/8

k = 7/4

y = 7/4 *x

when x=16

y = 7/4 * 16

y = 28
