Linear algebra

A straight line m_1 goes through the point (1,2,2), is parallel with the plane x + 3y + z = 1 and intersects with the straight line m_2 : (x,y,z) = (1+t,2-2t,-1+t).

a) Determine the equation on parametric form for the straight line m_1.
b) Determine (the smallest) angle between the lines m_1 and m_2.

Help Please!

$$\pi_1$$
is the plane we have

$$\pi_2$$

is an assumed plane that is parallel with pi_1

p_a is an arbritary point and p_o is the intersection point from line m_1

right?
