what is an equation of a line that passes through the points (-7,0) and (-6,-1)
---------
1 method:
Find the slope, m
Then, y-y1 = m*(x-x1) where (x1,y1) is either point.
===========
or,
| x   y   1|
|-6  -1   1| = 0
|-7   0   1|

( -7, 0 )
( -6, -1 )
+%28+y+-%28-1%29+%29+%2F+%28+x+-%28-6%29+%29+=+%28+0+-%28-1%29+%29+%2F+%28+-7+-%28-6%29+%29+
+%28+y+%2B+1+%29+%2F+%28+x+%2B+6+%29+=+1+%2F+%28-1%29+
+Multiply+both+sides+by+%7B%7B%7B+%28-1%29%2A%28+x+%2B+6+%29+
+-%28+y+%2B+1+%29+=+x+%2B+6+
+-y+-+1+=+x+%2B+6+
Multiply both sides by +-1+
+y+%2B+1+=+-x+-+6+
+y+=+-x+-7+
--------------------
check:
( -7, 0 )
+0+=+-%28-7%29+-+7+
+0+=+0+
OK
( -6, -1 )
+-1+=+-%28-6%29+-+7+
+-1+=+6+-+7+
+-1+=+-1+
OK
