Comparing Graph Table Equation

Two athletes are training over a two-week period to increase the number of push-ups each can do. Athlete A can do 16 pushups to start, and increases his total by 2 each day. Athlete B's progress is charted in the table. Who can do more pushups after two days and how many?

• Athlete B, 18

• Athlete A, 18

• Athlete A, 20

• Athlete B, 15

Which pizzeria makes more money?

• Pizzeria W

• Pizzeria L

• They both make the same amount

Review: What makes this graph not proportional?

• does not have a constant unit rate/slope

• is not straight line

• does not pass through (0,0)

Select all true statements

• A is not proportional but B is

• both pass through (0,0)

• y = 3x is the equation for table A

• y = 4x is the equation for table B

• if graphed, these tables would make the same line
