slope=change in y/change in x

slope=5-9/2-4
slope=-4/-2


Simplify -4/-2
slope= 2

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


m=%289-5%29%2F%284-2%29 Plug in y%5B2%5D=9, y%5B1%5D=5, x%5B2%5D=4, x%5B1%5D=2, ,


m=%284%29%2F%284-2%29 Subtract 5 from 9 to get 4


m=%284%29%2F%282%29 Subtract 2 from 4 to get 2


m=2 Reduce


So the slope of the line that goes through the points and is m=2
