For the 2 points: (4,1) and (1,4)
Solved by pluggable solver: Finding the slope


Slope of the line through the points (4, 1) and (1, 4)



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


m+=+%284+-+1%29%2F%281+-+4%29


m+=+%283%29%2F%28-3%29


m+=+-1



Answer: Slope is m+=+-1


So the slope is m=-1



For the 2 points: (-3,-5) and (-1,-2)
Solved by pluggable solver: Finding the slope


Slope of the line through the points (-3, -5) and (-1, -2)



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


m+=+%28-2+-+%28-5%29%29%2F%28-1+-+%28-3%29%29


m+=+%28-2+%2B+5%29%2F%28-1+%2B+3%29


m+=+%283%29%2F%282%29


Answer: Slope is m+=+3%2F2


So the slope is m=3%2F2



For the 2 points: (-7,-5) and (5, -6)
Solved by pluggable solver: Finding the slope


Slope of the line through the points (-7, -5) and (5, -6)



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


m+=+%28-6+-+%28-5%29%29%2F%285+-+%28-7%29%29


m+=+%28-6+%2B+5%29%2F%285+%2B+7%29


m+=+%28-1%29%2F%2812%29


Answer: Slope is m+=+-1%2F12


So the slope is m=-1%2F12
If you want to check your answers, or are really stuck with finding the slope, you can use this solver to find the slope through 2 points:
