How much are the owner's expenses for 10 days?
10 * 130 = $1300
How much money does the owner make selling pizzas per day?
200 * 3 = $600
How much money does the owner make selling sandwiches per day?
85 * 2 = $170
In one day, the owner sells 600 + 170 = $770 worth of pizza and sandwiches
Over the course of ten days, that is 10 * 770 = $7700
Profit = revenue - cost = 7700 - 1300 = $6400

To go from (-1,0) to (0,5) we have to go up 5 units and right one unit.
Rate of change means slope, which is change in y over change in x.
If our change in y is positive 5 and our change in x is positive one, we can put the rate of change as 5/1
This simplifies to 5.
