Options
- A(3,-1,-1)
- B(3,1,-1)
- C(3,-1,1)
- D(-3,-1,-1)
Correct answer
A. (3,-1,-1)
Step-by-step solution
Given line is x-1 2 = y-2 -3 = z+5 4 Let x-1 2 = y-2 -3 = z+5 4 = array ll & x-1=2 , y-2=-3 , z +5=4 & x=2 +1, y=-3 +2, z =4 -5 & 2 x+4 y- z =3 & 2(2 +1)+4(-3 +2)-(4 -5)=3 & 4 +2-12 +8-4 +5=3 & -12 =3-15 & =1 & x=3, y=-1, z =-1, array Required co-ordinates are: (3,-1,-1)
