Answer: OPTION B

Explanation:

The equation of a line that passes through the origin is the following:


y=mx

Where "m" is the slope of the line.

By definition, Proportional relationships have the following form:


y=kx

Where "k" is the Constant of proportionality.

Then, as you can notice, if you graph a Proportional relationship you will get a line that passes through the origin.

Therefore, based on the explained above, you can conclude that the option that shows a function that represents a Proportional relationship is the Option B.

Then, this is:


f(x)=(3)/(4)x
