    A.) y = ut - 1/2gt^2 + 12

    y = 6t - 1/2 (9.8) t^2 + 12

    y = 6t - 4.9t^2 + 12

    b.) The y-intercept is 12

    c.) The y-intercept represent the height of the ball at time t = 0

    d.) At the time the ball reaches the ground, y = 0

    -4.9t^2 + 6t + 12 = 0

    t = 2.29 seconds

    Therefore, it took the ball 2.29 seconds to reach the ground.
