The parametric equations of a line passing through the points A (3,4,-7) and B(1,-1,6) are

Options

  1. Ax =3+ , y =-1+4 , z =-7+6
  2. Bx =-2+3 , y =-5+4 , z =13-7
  3. Cx =3-2 , y =4-5 , z =-7+13
  4. Dx =3-2 , y =4-5 , z =-7+13

Correct answer

D. x =3-2 , y =4-5 , z =-7+13

Step-by-step solution

Equation of required line is aligned & x-3 1-3 = y-4 -1-4 = z+7 6+7 = (Say) & x-3 -2 = y-4 -5 = z+7 13 = & x=-2 +3, y=-5 +4, z=13 -7 aligned
