Show all your work. Always sketch axes in the standard way. 1. Find the parametric equation of the line and then of a line segment from A(1, 2,3) to B(5.0, l). 2. Identifyr and sketch the surface QIQ + z? = . Explain the position and the orientation of the surface. 3. Find an equation of the plane that contains point A(5,1,1) and the line that is given with parametric equation (3! _1! 2} + t
