Question

The variables x and y vary directly. Use the values to find the constant of proportionality, k. Then write an equation that relates x and y.

y=72; x=3
k=

y=

Answer 1

Answer:

y = kx

72 = 3k

24 = k

y = 24x

Hope this helps

Answer 2

Answer:

x+ky=O

3 + k 72=o

K72=--3

k=-3/72

K=l/24
