Type the correct answer in each box. If necessary, use / for the fraction bar(s). Emily works at a perfumery. She extracts 3 liters of essential oil for perfumes in 2 days.
Assurning Emily extracts essential oil at a constant rate, we can graph this relationship with time in days along the waxis and quantity of oil in liters along the y-axls.
The slope of the line representing this relationship is__
A point on this line that corresponds to the amount of oll Emily extracts after 5 days is (5,__
