The line through C (6,2) and D (1,3)
has slope [ change in y ] / [ change in x ]
--------------------
Any line perpendicular to this line
will have slope =
----------------------------
The unknown line goes through A( -3,5 )
I can use the general point-slope formula
----------------------
Check:
Does it go through A( -3,5 ) ?
OK
