Let's denote the first point (4,9) as . In other words, and

Now let's denote the second point (8,17) as . In other words, and



-------------------------



m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29 Start with the slope formula

m=%2817-9%29%2F%288-4%29 Plug in y%5B2%5D=17,y%5B1%5D=9,x%5B2%5D=8,x%5B1%5D=4


m=8%2F4 Subtract the terms in the numerator 17-9 to get 8. Subtract the terms in the denominator 8-4 to get 4

m=2 Reduce


---------------------
Answer:

So the slope of the line through the points (4,9) and (8,17) is m=2
