Question

Does the equation below represent a

direct proportion? If yes, identify
the constant of proportionality.
х = 6у
A. No
B. Yes, 36
C. Yes, -6
D. Yes, 1/6

Answer 1

yes / 1/6

Explanation:

Answer 2

Explanation:

The given equation is :

x = 6y ...(1)

Here,

x and y are variables and 6 is a constant number

It means,

x and y are related directly to each other i.e.

x ∝ y

or

x = ky .....(2)

Comparing equation (1) and (2)

k = 6

Hence, yes they are in direct proportion and the value of constant of proportionality is 6.
