How do you know if a number is directly proportional to another number?
in this question x is directly proportional to y
x=60
y=35
how is x directly proportional to y

x ∝ y

x = 12/7y

Step-by-step explanation:

Direct Proportion = x ∝ y

x = ky where k is the constant.

Substitute the values in:

60 = 35k

Now solve for k.

60/35 = k

k = 12/7

x = 12/7y

As the value of x increases the value of y increases proportionally.
