How can you determine if a relationship is proportional? Select all that apply

Multiply the x (independent variable) values and y (dependent variable) values and see if you get the same product for all

Multiply the y (dependent variable) values by the x(independent variable) values and see if you get the same product

Divide the x (independent variable) values by the y (dependent variable) values and see if you get the same quotient for al

Divide the y (dependent variable) values by the x (independent variable) values and see if you get the same quotient for all

See if there exists a constant multiplier, such that any x value(independent variable) multiplied by this value would give you a corresponding y (dependent variable) value
