4. Determine a vector equation for the plane that is parallel to the xy -plane and passes through the point (4, 1, 3). 5. Determine a scalar equation for the plane through the points M(1, 2, 3) and N(3,2, -1) that is perpendicular to the plane with equation 3x + 2y + 6z + 1 = 0. 6. Show that the line with parametric equations x = 6 + 8t, y = -5 + t, z =2 + 3t does not intersect the plane with equation 2x - y - 52 - 2 = 0. Answer the following and upload a picture of your work below. O
