Nahomy earns $15 each hour she tutors a student in spanish.

• Y = 15x

• 15

• 15x

• x = 15y

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

Y = x - 2

Y = 2x

• In y = x - 2 and in y = 2x, the value is 2 less than the value of x.

• In y = x - 2 and in y = 2x, the value is 2 times the value of x.

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

• In y = x - 2, the value of y is 2 times the value of x, and in y = 2x, the value of y is 2 less than the value of x.

Which situation can be represented by the equation y = 5x?
