REALLY NEED HELP Find an equation of the line passing through the pair of points. Write the equation in the form Ax + By = C
(0,0) (-1/5, 1/3)

Amass weighing 16 pounds stretches a spring 8/3 feet. the mass is initially released from rest from a point 2 feet below the equilibrium position, and the subsequent motion takes place in a medium that offers a damping force that is numerically equal to 1/2 the instantaneous velocity. find the equation of motion if the mass is driven by an external force equal to f(t)=cos(2t).
