You can put this solution on YOUR website!
+y+-+10+=+-4%2A%28+x+%2B+8+%29+
+y+=+-4%2A%28+x+%2B+8+%29+%2B+10+
+y+=+-4x+-+32+%2B+10+
+y+=+-4x+-+22+
This is in the form +y+=+mx+%2B+b+
where +m+ = slope, so
The slope is +-4+
------------------
If I say +x+=+0+, then
+y+=+-4%2A0+-+22+
+y+=+-22+, so you have the point
( 0,-22 )
-------------------
If I say +y+=+0+
+0+=+-4x+-+22+
+-4x+=+22+
+x+=+-11%2F2+
This is the point ( -11/2, 0 )
Now you can cnnect the points
Here's the plot:
