If a graph passes the vertical line test, then it represents...

• a relation

• not a function

Function? Linear?

• Function and Linear

• Function, but NOT Linear

• Not a function, but linear

• Not a function, so not linear

Answer explanation

Each input (x) goes to exactly one output (y) - Function

Constant rate of change (goes up by the same amount each time) - Linear

CCSS.HSF.LE.A.2

• Yes, it is linear

• No, it is not linear

Answer explanation

Any exponents on variables make a function non-linear.

CCSS.8.F.A.3

• Yes, it is linear

• No, it is not linear

Answer explanation

Solve for y if that helps you.

We can see that x has no exponents or radicals (it's "just x") so the function is linear.
