Homework Statement
Find the distance from the point Q to the line passing through the points P and R.
Homework Equations
r=r0+tv
D=|ax0 + by0 + cz0 + d| / sqrt(a2 + b2 + c2)
The Attempt at a Solution
To find the line:
(x,y,z) = (2,3,1) + t(3-2,1-3,1-1)
(x,y,z) = (2,3,1) + t(1,-2,0)
(x,y,z) = (2,3,1) + (t,-2t,0)
(x,y,z) = (t+2,3-2t,1)
My problem is I don't know how to format that answer so it fits in with my distance formula.
