Combine like terms
Answer: 7c + 7
-1-1 or 2-4 or 3-5 or 6-8 or 7-9 or 8-10
So the question ask to find and calculate the vector parametric equation r(t) for the line through the points P=(1,0,-2) and Q(1,5,1) for each given condition. And the possible vector parametric equation is <1,2,-2>+t/4<1,5,3>. I hope you are satisfied with my answer and feel free to ask for more
