Equation of a Line: r = ro + tv
The Attempt at a Solution
I'm not really sure how y-intercepts work in 3d and I'm having trouble even attempting a solution. My guess was the ro point <-1,0,-2> because the y coordinate is zero but I don't think that it would be that easy. Also, this is my first time posting a question on the Physics Forum site so please go easy on me if I messed anything up :)
