Estelle is raking leaves in her yard. After 1 hour, she has 2 bags of leaves. After 3 hours, she has 6 bags of leaves. Which graph represents Estelle's leaf raking progress?
Answer provided by our tutors
It is a graph of a line that goes trough the points (1, 2) and (3, 6):
y - 2 = (6 - 2)/(3 - 1)(x - 1)
y - 2 = 2(x - 1)
y = 2x - 2 + 2
y = 2x
