Cuckoos lay their eggs in the nests of other (host) birds. the eggs are then adopted and hatched by the host birds. but the potential host birds lay eggs of different sizes. does the cuckoo change the size of her eggs for different foster species? lengths (in mm) of cuckoo eggs found in nests of sparrows and robins were recorded.

Three students, javier, sam, and corrine, participated in a fundraiser where people donated a certain amount of money per lap that the student ran. each student also had some initial donations that were collected before the run. the equations that represent each student's total donation, y, based on the number of laps ran, x, is shown below. match each equation with the correct rate of change for that student.
