1.Find an equation for the plane containing the two (parallel)
lines v1 = (0, 1, −9) + t(4, 9, −3) and v2 = (9, −1, 0) + t(4, 9,
−3).
2.Find a parametrization for the line perpendicular to (6, −1,
1),parallel to the plane 6x + y
− 8z = 1,and passing through the point (1, 0,
−7).(Use the parameter t. Enter your answers as a
comma-separated list of equations.)
