Let's denote the first point (-4,1) as . In other words, and

Now let's denote the second point (3,8) 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=%288-1%29%2F%283--4%29 Plug in y%5B2%5D=8,y%5B1%5D=1,x%5B2%5D=3,x%5B1%5D=-4


m=7%2F7 Subtract the terms in the numerator 8-1 to get 7. Subtract the terms in the denominator 3--4 to get 7

m=1 Reduce


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

So the slope of the line through the points (-4,1) and (3,8) is m=1
