Slope of the line through the points (-2, 7) and (8, -1)



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+=+%28-1+-+7%29%2F%288+-+%28-2%29%29


m+=+%28-1+-+7%29%2F%288+%2B+2%29


m+=+%28-8%29%2F%2810%29


m+=+-4%2F5



Answer: Slope is m+=+-4%2F5





I'm not sure why there are two sets of answers, but it looks like the answer is D from the first set
