Problem with deriving oblique projection eq

Hi,
Can some body plz guide me how the values of xp and yp in case of oblique parallel projection is equal to:

xp= x + L cos (phi)
yp= y + L sin (phi)



This is mentioned in slide 50 of following link:

I also found that oblique projection is a sum of orthogonal projection and shear.

I would be glad to hear from some body in this regard.

Zulfi.
