Answer:
3x +15y +7z = 46
Step-by-step explanation:
The cross product of v = <2, 1, -3> and PQ = <-5, 1, 0> is <3, 15, 7>, the normal vector of the plane of interest. That plane contains P and Q, so the constant in the plane's equation will be ...
<3, 15, 7> · <3, 2, 1> = 46
The desired equation is ...
3x +15y +7z = 46
