Homework Statement
Given [tex]\pi: \begin{cases}l_1: \frac{x-2}{4}\ = \frac{y-1}{2}\ = \frac{z+5}{-4} &\\l_2: \frac{x+4}{-2}\ = \frac{y+1}{0}\ = \frac{z}{1} & \end{cases}[/tex] and the point [tex]M=(1,2,3)[/tex] outside the plane. Find the projection of the line [tex]M_1P[/tex] on plane [tex]\pi[/tex] where [tex]P[/tex] is the intersection point of lines [tex]l_1, l_2[/tex].2. The attempt at a solution
All I can do is that I can find the equation of plane [tex]\pi[/tex] but don't have any idea what to do next. So I need your help.
Thank you.
