can someone please help me with this problem? find the two points

easy way:
the 2nd line has pi/4 angle. So it's easy to find a line that is at distance 2 away from it (use some pythagoras for that). You will get two lines in this way - one lies below and other above the original line.
Now set either of these lines equal to your first line and the solutions will be the points you want.
