This graph describes the relationship between the volume of uncooked rice and the volume of the rice after it is cooked.

graph, horizontal axis, x (cups of uncooked rice), scale 0 to 30, by 4's. vertical axis, y (cups of cooked rice), scale 0 to 60, by 10's. line passes through origin, 20 comma 60.

1. Write an equation that reflects this relationship where  represents the volume in cups of uncooked rice and represents the volume in cups of the rice after it is cooked. 
2. Complete the table: 

   cups of uncooked rice	cups of cooked rice

Students are selling raffle tickets for a school fundraiser. They collect $24 for every 10 raffle tickets they sell.

1. Suppose is the amount of money the students collect for selling raffle tickets. Write an equation that reflects the relationship between and .
2. Label and scale the axes and graph this situation with on the vertical axis and on the horizontal axis. Make sure the scale is large enough to see how much they would raise if they sell 1,000 tickets.

   

A line is represented by the equation . For each point, determine if it is on this line.

Use a straightedge to draw two lines: one with slope  and one with slope .
