Slope of the line through the points (-9, 4) and (-8, 2)



m+=+%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+x%5B1%5D%29


m+=+%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+%28x%5B1%5D%29%29


m+=+%282+-+4%29%2F%28-8+-+%28-9%29%29


m+=+%282+-+4%29%2F%28-8+%2B+9%29


m+=+%28-2%29%2F%281%29


m+=+-2



Answer: Slope is m+=+-2

Slope is [ change in y ] / [ change in x ]
[ change in y ] = +4+-+2+=+2+
[ change in x } = +-9+-%28-8%29+=+-1+
-----------------------------------
[ change in y ] / [ change in x ] = +2%2F%28-1%29+
+2%2F%28-1%29+=+-2+
