y=12x is a direct proportion
Further explanation:
Let us define direct proportion.
"In direct proportion, one quantity varies directly with other quantity or the ratio between both quantities is always constant.
So,
Given:
y =12x
The general form of direct proportion is:
x=ky or y = kx
Here k is the constant of proportionality
Comparing the given variation with general form
y =12x
k = 12
So, the given variation is direct.
