Prove that the lines `(x+1)/3=(y+3)/5=(z+5)/7a n d(x-2)/1=(y-4)/4=(z-6)/7`are coplanar . Aslo, find the plane containing these two lines.A. `x-2y+z=0`B. `x+2y-z=0`C. `x-2y+z=1`D. none of these

Answer» Correct Answer - A
The equation of the plane containig the given lines is
`|(x+1,y+3,z+5),(3,5,7),(1,4,7)|=0impliesx-2y+z=0`
