Find parametric equations for the line described below The l
     Find parametric equations for the line described below.  The line through the points P(-1, -1, -3) and Q(7, 5, 7)  x = t + 8, y = t + 6, z = -3t + 10  x = 8t + 1, y = 6t + 1, z = 10t + 3  x = 4t + 8, y = 2t + 6, z = -3t + 10  x = t - 8, y = t - 6, z = -3t - 10  x = 8t - 1, y = 6t - 1, z = 10t - 3 
  
  Solution
P=(-1,-1,-3) Q=(7,5,7)
position vector is <7-(-1),5-(-1),7-(-3)> = <8,6,10>
We can take either of the points to find the parametric equations
Lets take point P
Therefore the parametric equations are
x=-1+8t,y=-1+6t,z=-3+10t
Correct option is E
