Homework Statement
Find an equation of the plane that passes through the point (6,0,-2) and contains the line x=4-2t, y=3+5t, z=7+4t.
Homework Equations
The Attempt at a Solution
Here's what I did:
I substituted t=2 to get:
x=0, y=17, z= 15
So in total, we have three points that the plane contains: P1(6,0,-2), P2(4,3,7), P3(0,17,15)
Vector P1P2=<-2,3,9>
Vector P1P3=<-6,17,17>
I took a cross product of these vectors to get <-102,-20,-16>
I used the point P1(6,0,-2) to obtain:
-102(x-6)-20(y-0)-16(z+2)=0
But the solution is 33(x-6)-10(y-0)-4(z+2)=0
I'm unable to understand what I did wrong. I'd really appreciate any help!
