Decide which of the following equations represents a proportional relationship.(1 point) Responses y=x3−3 y equals Start Fraction x over 3 End Fraction minus 3 y=13x y equals Start Fraction 1 over 3 End Fraction x y=x+3 y equals x plus 3 y=3x+1

Answer 1

The equation y=3x+1 represents a proportional relationship because the value of y is directly proportional to the value of x with a constant of proportionality of 3.
