Answer :
The equations that represent proportional relationships are y = x/3, y = (1/4)x and y = 2x
A relationship can either be a direct, inverse, or even joint relationship
For instance, if y is directly proportional to x, hence;
y = kx
k is the constant of variation
Similarly, if y is inversely proportional to x, hence;
y = k/x
k is the constant of variation
From the given options, we need to find the expressions that are similar to the equations above.
