Use the general point-slope formula
+%28+y+-+%28-5%29+%29+%2F+%28+x+-+%28-3%29+%29+=+1%2F2+
+2%2A%28+y+%2B+5+%29+=+x+%2B+3+
+2y+%2B+10+=+x+%2B+3+
+2y+=+x+-+7+
+y+=+%281%2F2%29%2Ax+-+7%2F2+
---------------------
check answer:
Does it pass through ( -3,-5 )?
+-5+=+%281%2F2%29%2A%28-3%29+-+7%2F2+
+-10+=+-3+-+7+
+-10+=+-10+
OK
