This is the last question I need help on, thanks for helping me on this.

In what form is the following linear equation written y=9x+2

Which of the following is another way to express the difference between -5 and 8?

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).
