Find the equation of theplane passing through the line `(x-1)/5=(y+2)/6=(z-3)/4`and point `(4,3,7)dot` |
Answer» Any plane through `(x-1)/(5) = (y+2)/(6)=(z-3)/(4)` is `" "A(x-1)+B(y+2)+C(z-3)=0" "`(i) where `5A+6B+4C=0" "` (ii) Also, the plane passes through `(4, 3, 7)`. Therefore, `" "3A+5B+4C=0" "` (iii) By (ii) and (iii), `(A)/(4)=(B)/(-8)= (C)/(7)` Therefore, the plane is `" "4(x-1)-8(y+2)+7(z-3)=0` or `" "4x-8y+7z= 41`. |
