1) graph this situation

2) how should you label your axes?

3) does this graph make a line?why does this make sense? 

4) what is the slope ? what does the number mean? 

5) how many burgers can you get with $40?

Answer 1

1. Ill let you create the graph.

2. Label x-axis whoppers and y-axis $

3. Yes it makes a line. You are paying a steady amount per burger, and therefore creating a straight line on your graph.

    If the burgers changed cost you would not have a straight line. You would also have changing slopes.

4. Slope is 2.5 This means for every burger you buy you pay 2.5 dollars.

5. 2.5x=40 Solve for x. x=16
