Two airplanes mapped their courses on a coordinate grid. the first plane followed a path of y = 3x - 8. the second airplane flew it's daily flight on the path -6 + 2y = -16. describe the similarities or the differences in the planes' path.

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.
