Hi
Using the point-slope formula, m+=%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+x%5B1%5D%29
If a line passes through the points (2, 7) and (7, 9), its slope is 2/5.
(2, 7) and
(7, 9) m = -2/-5 = 2/5

Solved by pluggable solver: Finding the slope


Slope of the line through the points (2, 7) and (7, 9)



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


m+=+%289+-+7%29%2F%287+-+2%29


m+=+%282%29%2F%285%29


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