Use the graph to find the unit rate

2.4 potatoes/pound

The unit rate is the slope of the line. The slope of the line is ...

... (change in y-value)/(change in x-value)

... = (36 potatoes - 12 potatoes)/(15 pounds - 5 pounds)

... = (24 potatoes)/(10 pounds)

... = 2.4 potatoes/pound

The relationship here is proportional, so the line goes through the point (0, 0) and the unit rate can be figured from any point:

... (12 potates)/(5 pounds) = (24 potatoes)/(10 pounds) = (36 potatoes)/(15 pounds) = 2.4 potatoes/pound

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
