Hey guys! My class never learned how to do Cartesian coordinates, so I am rather lost as to how to do this question!

Question

Find the Cartesian equation o the plane that contains the line and is parallel to the line

Solution

I don't understand what the means. Can I use this and put it into vector or parametric form? If I knew how to do that I could find the solution to the question. Especially vector form.

Thank you!
