How do I graph this then find the solution?

Ok for the first equation 2 is the y-intercept so you put 2 in the y-axis. The for 1/3 is the slope. And the fraction is rise/run so you rise one unit from where the 2 point is and after that you run to the right 3 units and place a point.

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
