slope = ( change in y ) / ( change in x )
slope = +%28+8+-+4+%29+%2F+%28+5+-+%28-3%29+%29+
slope = +4%2F8+
slope = +1%2F2+

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=5 and y%5B2%5D=8.


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


m=%288-4%29%2F%285--3%29 Plug in y%5B2%5D=8, y%5B1%5D=4, x%5B2%5D=5, and x%5B1%5D=-3


m=%284%29%2F%285--3%29 Subtract 4 from 8 to get 4


m=%284%29%2F%288%29 Subtract -3 from 5 to get 8


m=1%2F2 Reduce


So the slope of the line that goes through the points and is m=1%2F2
