which point lies on the origin side of the plane x-2y+2z+3=0 ?a) (1,2,-7) b) (2,3,-2) c) (1,1,-1) d) (2,1,3) Share with your friends Share 1 Anuradha Sharma answered this x-2y+2z+3=0Let m = x-2y+2z+3Now at origin0,0,0m = 3>0And at 1,2,-7 we get, m = 1-4-14+3=-14<0and at 2,3,-2 we get, m = 2-6-4+3=-5<0and at 1,1,-1 we get, m = 1-2-2+3=0and at 2,1,3 we get, m = 2-2+6+3=9>0here we can see that 1,1,-1 value is more closer to value at origin so this point is origin side 0 View Full Answer
