    Can someone explain how to do this.

    I tried using the formula

    a-c = 6i-7j

    and bxd is the direction vectors multiplied but one of them doesn't have a direction?

    Im confused ;(

    The direction of the first line is j since s is the scalar product. It would look like this: [3i +0j -k +s(0i +j +0k)]

    I see you mistook the s for a 5 xD.

    Like Pyslocke said, s is the parameter for the first vector equation. Here is what you do (I left out doing b x d because you should be able to do it.)

    I was unable to put the LaTeX into the thread, for some reason the commands don't work here...?
