Unformatted text preview: And 4x+y-3z=7Ignore 2 and 7, do cross==4i+26j+14k Eq of plane through (1,1,1)(0,1,2)(2,-5,0) A(x-xo)+b(y-yo)+c(z-zo) = oP1P2=-i+0j+k P1P3 = i-6j-k.n = P1P2 X P1P3=6i+6k Find unit vector to plane 6i+6k. SQRT(6^2+6^2)=SQ(72) so n = n/(//n//) OR 6/SQ(72)*(i+k) PLUG into equation P1=(1,1,1).6(x-1)+6(z-1)=0 6x+6z=12. .therefore x+z=12...
