Maureen and michael want to make cupcakes for their teachers. they have 6 tubes of frosting, and each cupcake requires 2/7 of a tube of frosting. how many cupcakes can they make? show how you know.

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

f(x) = y

f(-3) = -5
