Question
Find the equation of the plane passing through the three points.
P =(4,-1,8), Q = (1, 1, 1),
R=(3, 1,-2)
Consider the proposed solution for the equation of the line passing through all three points.
Find n = =OP XOR
= (4 – 1, (−1) — 1, 8 − 1) × (3 – 1, 1 – 1, (−2) – 1)

Then, n. (x, y, z) = d where d = OP OR
= (3,-2,7) (2,0,-3)
= -15
Therefore, the equation of the line is
6x + 23y + 4z = -15
Is this the correct equation of the line? If not, explain?
