1. (-2,5),(8,-4)
Solved by pluggable solver: Finding the slope


Slope of the line through the points (-2, 5) and (8, -4)



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+=+%28-4+-+5%29%2F%288+-+%28-2%29%29


m+=+%28-4+-+5%29%2F%288+%2B+2%29


m+=+%28-9%29%2F%2810%29


Answer: Slope is m+=+-9%2F10




2. (6,7),(2,4)

Solved by pluggable solver: Finding the slope


Slope of the line through the points (6, 7) and (2, 4)



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


m+=+%284+-+7%29%2F%282+-+6%29


m+=+%28-3%29%2F%28-4%29


m+=+3%2F4



Answer: Slope is m+=+3%2F4




3. (-4,-5),(-3,-9)

Solved by pluggable solver: Finding the slope


Slope of the line through the points (-4, -5) and (-3, -9)



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


m+=+%28-9+-+%28-5%29%29%2F%28-3+-+%28-4%29%29


m+=+%28-9+%2B+5%29%2F%28-3+%2B+4%29


m+=+%28-4%29%2F%281%29


m+=+-4



Answer: Slope is m+=+-4




4. (6,-2),(-3,7)

Solved by pluggable solver: Finding the slope


Slope of the line through the points (6, -2) and (-3, 7)



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


m+=+%287+-+%28-2%29%29%2F%28-3+-+6%29


m+=+%287+%2B+2%29%2F%28-3+-+6%29


m+=+%289%29%2F%28-9%29


m+=+-1



Answer: Slope is m+=+-1
