We are given points

A = [2; 4; 0]

and

B = [4; 7; 6]

. Find parametric equations of a line

q

, which is the orthogonal projection of the line

A B

into the coordinate plane

x y

.

\begin{aligned} p : x & = 4 + 2 t, \\ y & = 7 + 3 t, \\ z & = 0; t \in R \end{aligned}

\begin{aligned} p : x & = 2 + 4 t, \\ y & = 4 + 7 t, \\ z & = 6 t; t \in R \end{aligned}

\begin{aligned} p : x & = 4 + 2 t, \\ y & = 7 + 3 t, \\ z & = 6; t \in R \end{aligned}

\begin{aligned} p : x & = 2 - 2 t, \\ y & = 4 - 3 t, \\ z & = - 6 t; t \in R \end{aligned}
