Answer:
Kx
Explanation:
A proportional relationshp is one of the kind y = Kx, where K is a constant. That means, that the value of y is found multiplying the value of x times the proportionality constant K. You also must know the graphs y = Kx is a straight line with slope K and y-intercept 0, that is a straight line that passes through the origin. So, for the graph represent a proportional relationship, it has to a straight line that passes through the origin, which is the option B. Answer: option B. Yes, because it is a straight line that passes through the origin.
