(-4,5), (0,-2)
The formula is:
+%28y+-+%28-2%29%29+%2F+%28x+-+0%29+=+%28+5+-%28-2%29%29+%2F+%28+-4+-+0+%29+
+%28y+%2B+2%29+%2F+x+=+%28+5+%2B+2%29+%2F+%28+-4+%29+
+%28y+%2B+2%29+%2F+x+=+-7%2F4+
Multiply both sides by 4x
4%2A%28y+%2B+2%29+=+-7x+
+4y+%2B+8+=+-7x+
+7x+%2B+4y+=+-+8+
check:
(-4,5)
+7x+%2B+4y+=+-+8+
+7%2A%28-4%29+%2B+4%2A5+=+-+8+
+-28+%2B+20+=+-8+
+-8+=+-8+
OK
(0,-2)
+7x+%2B+4y+=+-+8+
+7%2A0+%2B+4%2A%28-2%29+=+-+8+
+0+-+8+=+-8+
+-8+=+-8+
OK
