Which of the following equations represents a toy-making rate, in toys per hour, that is half that of Nicolas's toy-making rate?

t = 2h


t = 4h


t = 8h


t = 16h

Answer 1

Read two points on the graph (for example (2,16)), so Nicolas's rate = rise/run = 16/2 = 8 toys/hour. Half that rate is 4 toys/hour, so the equation is t = 4h.
