Question

Both questions are required, I have my solution but only want to fact check my work. 

Show that the equation of a straight line in space, represented in the
Cartesian basis, is given by the following set of parametric equations:
Q5:
b3
X3 =
(x1 – a1) + az
b1
b2
X2 =
- (x1 – a1) + az
Where x; are the coordinates of an arbitrary point along the line, a; are the coordinates
at the start of the line and b; is the coordinates corresponding to the direction that the
line is parallel to.
Hint: Write a vector equation that relate the position vectors x, a and b.
Hence, write the equation of the straight line that starts from a = e1 + e2 + e3 parallel
to b = 2e1 + e2 + 2e3. Find the coordinates where the line intersects the x1–x2,
X2-X3 and x1-x3 planes.
