Consider z1 and z2 in the complex plane. On a coordinate plane, the y-axis is labeled imaginary and the x-axis is labeled real. Point Z 1 is (3, 1), Z 2 is (negative 2, negative 5). Point A is at (1, negative 4), B is (5, 5), C is (negative 3, 1), and D is (4, negative 2). A dotted line goes from z 1 to (0, 0), and then down to point z 2.

Which point represents z1 + z2?

A
B
C
D

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.
