Discrete Math: Equations of a Line

posted by .

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).

I don't know how to solve this problem.

  • Discrete Math: Equations of a Line -

    let M be the midpoint
    then M =(3,1,3/2)

    then a direction vector of the line is
    [3-0,1+1,3/2-1] = [3,2,1/2] or [6,4,1}

    possible parametric equations:

    x = 0 + 6t
    y = -1 + 4t
    z = 1 + t
