    Lines in a Plane 7

    Find parametric equations for the line that passes through the point (0,-1,1) and the midpoint of the line segment from (2,3,-2) to (4,-1,5).

    This is my work below. Can someone confirm to see if I have the correct answer? There is no answer in the back for this question. Please let me know. Thanks for your help.

    m=(3,1,1.5)
    d=(3,2,0.5)

    x=3t
    y=-1+2t
    z=1+0.5t

    It would have been more complete to say that the midpoint of the line segment from (2,3,-2) to (4,-1,5) was (3, 1, 1.5) and show how you got m and d.
