The question states the the graph is non-vertical. This mean the graph is either rise of falling. This also means that the value of function is not same at more than one value of x.

Another hint the question gives us is that the graph is a straight line. So this means we have a straight line rising or falling with some angle or a slope. This signifies a linear function.

It would have been a non-function if the line was a vertical one.
It would have been a non-linear function if the line was not straight.
The graph of exponential function is not straight.

Hence the answer to this question is Linear Function

Non vertical is referring to it being a function when you do the vertical line test. A vertical line will fail. Since the line is straight the answer would be A. Linear function.

The town librarian bought a combination of new-release movies on DVD for $20 and classic movies on DVD for $8. Let x represent t

Galina-37 [17]

Answer:

x = 1, y = 60

Step-by-step explanation:

Value of new-releases (x) = $20 each

Value of classic (y) = $8 each

Total budget = $500

Equation : 20x + 8y = 500

The librarian wants to purchase maximum DVDs. She can get more DVDs of classic movies for $8 as they are less costly.

Lets assume the librarian buys at least one new-release DVD.
