The cost, y, of a frult drink is proportional to x, the number of fruit drinks. The constant of proportionality Is 3.25. Which will check that y is proportional to x?Graph y = 3.25 x and check that the graph is a straight line that goes through (1, 3.25).Graph y = 3.25 x and check that the graph is a straight line that goes through (0, 0).Graph x = 3.25 y and check that the graph is a straight line that goes through (0,0).Graph y = 3.25 x and check that the graph is a straight line that goes through (0, 1).
