Question

x varies directly as y. If x = 30, then y = 15. Then the constant of variation will be ​

Answer 1

Answer:

For a linear relationship,   y = kx     where k is the proportionality constant

For the data given,   k = 30/15 = 2

and for the question, y = kx = 2*10 = 20

Step-by-step explanation:

Answer 2

Answer:

x/y=2

Step-by-step explanation:

since x is directly proportional to y

hence, x/y = constant
