Let L be the line with parametric equations x=2-2t y=-3 z=3-t Find the vector equation for a line that passes through the point P=(-4, -3, -7) and intersects I. at a point that is distance 4 from the point Q=(2, -3, 3). Note that there are two possible correct answers. Use the square root symbol "H\" where needed to give an exact value for your
