The question asks:
Which of the points P(3,2,1), Q(2,3,1),R(1,4,1) lie on the plane
3(x-1)+4y-5(z+2)=0?

I know this is a pretty easy problem...but I am drawing a blank on where to start? Should I form vectors from each point ? If so, then what?

A little lost!

Thanks

If the point lies on the plane, then it is a solution to the equation.
