Algebraic Representations

Which statement describes the relationship between x and y in these two equations?

• In y = 2x the value of y is 2 more than the value of x, and in y = x + 2 the value of y is twice the value of x.

• In y = 2x and in y = x + 2, the value of y is 2 more than the value of x.

• In y = 2x and in y = x + 2, the value of y is twice the value of x.

• In y = 2x the value of y is twice the value of x, and in y = x + 2 the value of y is 2 more than the value of x.
