An antique dealer stores her trunks in a shed
that is 80 square feet. There are two sizes of
trunks. The large trunk takes up 10 square
feet of space and the small trunk takes up 5
square feet of space. The shed can hold a
maximum of 10 trunks. If x is the number of
large trunks and y is the number of small
trunks, which of the following constraints
below will NOT be used in determining how
many trunks can be stored?

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)
