The equation y = 3x and y = 12x represents a proportional relationship.

Because i n a proportional relationship, the graph should pass the 0,0 coordinate.

It means if you put x=0 to the equation, the result would be y=0. The graph will go in format of y=mx and if we put x = 0 in both equations we get y = 0

and in other two equations if you put x = 0 you will not get y = 0.
