Use general point-slope formula
+%28+y+-+1+%29+%2F+%28+x+-+3+%29+=+%28+10+-+1+%29+%2F+%28+0+-+3+%29+
+%28+y+-+1+%29+%2F+%28+x+-+3+%29+=+9+%2F+%28-3%29+
+%28+y+-+1+%29+%2F+%28+x+-+3+%29+=+-3+
+y+-+1+=+-3%2A%28+x+-+3+%29+
+y+-+1+=+-3x+%2B+9+
+y+=+-3x+%2B+10+
----------------
check:
(3,1)
+y+=+-3x+%2B+10+
+1+=+-3%2A3+%2B+10+
+1+=+-9+%2B+10+
+1+=+1+
OK
(0,10)
+y+=+-3x+%2B+10+
+10+=+-3%2A0+%2B+10+
+10+=+10+
OK
