(4,4)
+m+=+-5%2F7+
The formula is:
+%28y+-+4%29+%2F+%28x+-+4%29+=+-5%2F7+
Multiply both sides by +7%2A%28x-4%29+
+7%2A%28y+-+4%29+=+-5%2A%28x+-+4%29+
+7y+-+28+=+-5x+%2B+20+
+7y+=-5x+%2B+48+
+y+=+%28-5%2F7%29%2Ax+%2B+48%2F7+
check:
Does the line go through (4,4) ?
+y+=+%28-5%2F7%29%2Ax+%2B+48%2F7+
+4+=+%28-5%2F7%29%2A4+%2B+48%2F7+
+28+=+-20+%2B+48+
OK
