Note: is the first point . So this means that x%5B1%5D=-3 and y%5B1%5D=0.
Also, is the second point . So this means that x%5B2%5D=4 and y%5B2%5D=3.


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


m=%283-0%29%2F%284--3%29 Plug in y%5B2%5D=3, y%5B1%5D=0, x%5B2%5D=4, and x%5B1%5D=-3


m=%283%29%2F%284--3%29 Subtract 0 from 3 to get 3


m=%283%29%2F%287%29 Subtract -3 from 4 to get 7


So the slope of the line that goes through the points and is m=3%2F7
