Two equations are shown below. Which of the statements best explains the relationship between the equations?

• In y = x + 3, the value of y is 3 more than the value of y = 3x.

• In y = 3x, the value of y is 3 times the value of y in the equation y = x + 3.

• In y = 3x, the value of y is three times the value of x, and in y = x + 3 the value of y is three less the value of x.

• In y = 3x, the value of y is three times the value of x, and in y = x + 3, the value of y is three more than the value of x.
