Use general point-slope formula
+%28+y+-+5+%29+%2F+%28+x+-+4+%29+=+%28+8+-+5+%29+%2F+%28+6+-+4+%29+
+%28+y+-+5+%29+%2F+%28+x+-+4+%29+=+3+%2F+2+
+2%2A%28+y+-+5+%29+=+3%2A%28+x+-+4+%29+
+2y+-+10+=+3x+-+12+
+2y+=+3x+-+2+
+y+=+%283%2F2%29%2Ax+-+1+
------------------------
check:
( 4,5)
+5+=+%283%2F2%29%2A4+-+1+
+5+=+6+-+1+
+5+=+5+
------------------
(6,8)
+8+=+%283%2F2%29%2A6+-+1+
+8+=+9+-+1+
+8+=+8+
OK
