In physics lab, Tyee attaches a wireless sensor to one of the spokes of a bicycle wheel spinning freely on its axle. The graph below shows the sensor's height above the ground, in centimeters, over time $$t$$, measured in seconds. Write an equation in terms of $$y$$, height in centimeters above the ground, and $$t$$, time in seconds, to represent the given context.
