Emily works at a perfumery. She extracts 3 liters of essential oil for perfumes in 2 days. Assuming Emily extracts essential oil at a constant rate, we can graph this relationship with time in days along the x-axis and quantity of oil in liters along the y-axis. The slope of the line representing this relationship is
.
A point on this line that corresponds to the amount of oil Emily extracts after 5 days is (5,
).
