In an ordered pair the x-coordinate represents the number of octagons, and the y-coordinate represents the total number of sides. if the x-coordinate is 9, what is the y-coordinate?

Quick graph the line for y+2=32(x+4) on the coordinate plane. does anyone know the cordinates will mark brainliest.

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.

Which graph or graphs appear to show a sinusoid? < me asap !
