The line of intersection of the planes x+y+z-1=0, 4x+y-2z+2=0 passes through the point

a
1,0,1
b
2,0,1
c
(0,0,1)
d
(1,0,0)

detailed solution

Correct option is C

The equations of the given plane are x+y+z-1=0, 4x+y-2z+2=0Substitute y=0 in the above equations and then solve for the other two variables.Hence, x=0,z=1One of the points on the line of intersection of two planes is 0,0,1
