Use the point-slope formula
+%28+y+-+4+%29+%2F+%28+x+-+3+%29+=+%28+6+-+4+%29+%2F+%28+4+-+3+%29+
+%28+y+-+4+%29+%2F+%28+x+-+3+%29+=+2+%2F+1+
+y+-+4+=+2%2A%28+x+-+3+%29+
+y+-+4+=+2x+-+6+
+y+=+2x+-2+
-------------
check:
(3,4)
+y+=+2x+-2+
+4+=+2%2A3+-2+
+4+=+6+-+2+
+4+=+4+
OK
(4,6)
+6+=+2%2A4+-+2+
+6+=+8+-+2+
+6+=+6+
OK
