Find the slope of the line (-5,3) and (7,9)
-------------
slope = (9-3)/(7--5) = 6/12 = 1/2

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


m=%289-3%29%2F%287--5%29 Plug in y%5B2%5D=9, y%5B1%5D=3, x%5B2%5D=7, and x%5B1%5D=-5


m=%286%29%2F%287--5%29 Subtract 3 from 9 to get 6


m=%286%29%2F%2812%29 Subtract -5 from 7 to get 12


m=1%2F2 Reduce


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