Question

4. If ‘x’ and ‘y’ are in a direct proportion then which of the following is

correct?

(a) x – y = constant

(b) x + y = constant

(c) x × y = constant

(d)
x/y constant​

Answer 1

Answer:

Hey there!

Step-by-step explanation:

If two variables varies directly then,

x/y=K(constant)

Suppose if we take and example:-

9/27=10/30

If we writ them in simplest form, we get

1/3=1/3

That is a constant
