In Exercise, use a computer to draw a direction field for the given first-order differential equation. Use the indicated bounds for your display window. Obtain a printout and use a pencil to draw a number of possible solution trajectories on the direction field. If possible, check your solutions with a computer.

y' = t – y + 1, R = {(t, y): –6 ≤ t ≤ 6, –6 ≤ y ≤ 6}
