Among the following a line passing through origin is (x, y ≠ 0) 

Correct Answer - `p=(-3)/(2)`

Correct Answer - `vec(r ) =(2hat(i) +hat(j) -5hat(k)) +lambda(hat(i) +3hat(j)-hat(k)) ,(x-2)/(1)=(y-1)/(3)=(z+5)/(-1)`

Correct Answer - `(x-1)/(3)=(y+2)/(-4) =(z-3)/(5) , vec( r) =(hat(i) -2hat(j) +3hat(k)) +lambda (3hat(i) -4hat(j) +5hat(k))`

Correct Answer - `(x-1)/(2)=(y-2)/(3)=(z+4)/(6),vec(r ) =(hat(i) +2hat(j) -4hat(k)) +lambda(2hat(i) +3hat(j) +6hat(k))`

Correct Answer - x=9

Correct Answer - `(i)(5)/(8), 5x-8y-31=0 (ii)(-5)/(3), 5x+3y+2=0` (iii)`(3)/(5),3x-5y=0 (iv)0,y=b`
