Any one want to talk to meh

Find parametric equations for the line. (enter your answers as a comma-separated list of equations. let x, y, and z be functions of t.) the line in the direction of the vector 5 i + 5 j − 6k and through the point (−4, 4, −2).

Which expression will have the same sum as 3_8 + 1/4?

Me. i can't figure out this question. give an explanation too. .
