    are those equa;l signs spoose to be (+) signs?

    the normal vector appeart to be <3,2,6> assuming those are sposed to be (+) signs

    the equation appears to be: 3x-6 +2y-4 +6z+18 = 0 3x + 2y +6z +8 = 0 would be the eqaution of the plane

    its looks line parametric representation of the line... what is the topic of your study?

    To find the parametric equations of the line passing through the point (2,2,-3) and parallel to the vector <3,2,6>. We first find the vector equation of the line. Here, r_0=<2,2,-3> and v=<3,2,6>. Thus, the line has vector equation r=<2,2,-3>+t<3,2,6>. The parametric equations of the line are: x=2+3t, y=2+2t, and z=-3+6t. [B]
