Sample: the first question, solved
What piece of information, together with a point on a line, is needed to write its vector equation?
📘 Worked solution
✓A direction vector, since r=r₀+td requires a point r₀ and a direction d to describe every point on the line as t varies.
And one from the hard end
"Find the vector, parametric, and symmetric equations for a 3D line through A(2,−1,3) and B(5,2,−1)."
