Step-by-step explanation:
If y is proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k divide both sides by x
k = 
This value must be constant for all ordered pairs, thus
k =
= 
k =
= 
k =
= 
k = 
Since k is constant for all ordered pairs then y is proportional to x
