Both rows increase by 13 Entries in delivery line are $5 more than pick up Pick Up line can be scaled up Delivery line cannot be scaled up! p. 46

The 13 in the equation shows up in the increase in the pick up line. This does NOT show up in the delivery line. That equation would be:

b. How are the graphs similar? How are they different? Both graphs are straight lines The lines are parallel The pick up line starts at (0, 0) The delivery line starts at (0, 5)

One Pizza Delivery: (1, 18) Pick Up: (1, 13) Zero Pizza Delivery: (0, 5) Pick Up: (0, 0)

n = 5C C = 0.2n $0.20 per orange5 oranges per dollar

(1, 5) = 5 oranges for $1 (1, 0.20) = $0.20 for one orange

d miles 1 gallon 600 miles 20 gallons = d = 30 miles 1 mile g gallons 600 miles 20 gallons = g = gallon

Unit Rate: 30 miles per gallon

1 gallon = 30 miles 0 gallons = 0 miles

600 miles 20 gallons = x = 120 miles 600 miles 20 gallons = x miles 4 gallons x miles 1 gallon 30 miles 1 gallon = 120 miles 4 gallons = Both are correct! You could also look at the graph, make a rate table, or use the equation, d = 30g and substitute 4 for g!
