The vector ORTHOGONAL to the plane 4x + 3y - 3z = 1 is the vector U = (4,3,-3). The vector equation the problem asks for is V(t) = P + U*t, where P is the given point (4,-1,-3) and "t" is the parameter. The parametric equation consists of the THREE SCALAR equations x(t) = 4 + 4t, y(t) = -1 + 3t, z(t) = -3 - 3t.
