Comparing Tables, Equations and Graphs

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

• In y = 5x and y = x + 5, the value of y is 5 times the value of x.

• In y = 5x and y = x + 5, the value of y is 5

  more than the value of x.

• In y = 5x the value of y is 5 more than the

  value of x, and in y = x + 5 the value of y is

  5 times the value of x.

• In y = 5x the value of y is 5 times the value

  of x, and in y = x + 5 the value of y is 5 more than the value of x.
