Use the slope-intercept form y+=+mx+%2B+b
-3+=+m%2A7+%2B+2
7m+=+-5
m+=+-%285%2F7%29
The whole equation is
y+=+-%285%2F7%29x+%2B+2
In standard form:
%285%2F7%29x+%2B+y+-+2+=+0
5x+%2B+7y+-+14+=+0 answer
check:
does the line go through (7,-3)?
5%2A7+%2B+7%2A%28-3%29+-+14+=+0
35+-+21+-+14+=+0
35+-+35+=+0
0+=+0
OK
