Use the general point-slope formula
given: ( 4,22 ) and ( 2,12 )
+%28+22+-+12+%29+%2F+%28+4+-+2+%29+=+%28+y+-+12+%29+%2F+%28+x+-+2+%29+
+10+%2F+2+=+%28+y+-+12+%29+%2F+%28+x+-+2+%29+
+5+=+%28+y+-+12+%29+%2F+%28+x+-+2+%29+
+y+-+12+=+5%2A%28+x-2+%29+
+y+=+5x+-+10+%2B+12+
+y+=+5x+%2B+2+
---------------
check:
( 4,22 )
+y+=+5x+%2B+2+
+22+=+5%2A4+%2B+2+
+22+=+22+
--------------
( 2,12 )
+y+=+5x+%2B+2+
+12+=+5%2A2+%2B+2+
+12+=+12+
OK
