For a graph of a relation to pass the vertical line test the line may only touch the graph:

• one time.
• two times.
• three times.
• not at all.

A relation is a set of:

• pictures.
• random numbers.
• geometric figures.
• ordered pairs.

Write 2x+y=24 in function notation.

• f(x) = 2x-24
• f(x) = -2x+24
• f(x) = 1/2 x + 24
• f(x) = -1/2 x + 24
