Note: is the first point . So this means that x%5B1%5D=3 and y%5B1%5D=4.
Also, is the second point . So this means that x%5B2%5D=1 and y%5B2%5D=2.


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


m=%282-4%29%2F%281-3%29 Plug in y%5B2%5D=2, y%5B1%5D=4, x%5B2%5D=1, and x%5B1%5D=3


m=%28-2%29%2F%281-3%29 Subtract 4 from 2 to get -2


m=%28-2%29%2F%28-2%29 Subtract 3 from 1 to get -2


m=1 Reduce


So the slope of the line that goes through the points and is m=1

slope = ( change in y ) / ( change in x )
slope = ( 4 - 2 ) / ( 3 - 1 )
slope = 2/2
slope = 1
