You can put this solution on YOUR website!
The points where the lines intersect the x-axis and the y-axis are easy to find.

On the x-axis, y=0 , so all you have to find is he value of x when y=0 .
For the graph of green%28x%2B10y=105%29 ,
system%28x%2B10y=105%2Cy=0%29 --> system%28y=0%2Cx%2B10%2A0=105%29 --> system%28y=0%2Cx%2B0=105%29 --> highlight%28system%28y=0%2Cx=105%29%29 .
For the graph of red%28x%2B25y=255%29 ,
system%28x%2B25y=255%2Cy=0%29 --> system%28y=0%2Cx%2B10%2A0=255%29 --> system%28y=0%2Cx%2B0=255%29 --> highlight%28system%28y=0%2Cx=255%29%29 .

On the y-axis, x=0 , so all you have to find is he value of y when x=0 :
system%28x=0%2Cx%2B10y=105%29 --> system%28x=0%2C0%2B10y=105%29 --> system%28x=0%2C10y=105%29 --> system%28x=0%2Cy=105%2F10%29 --> highlight%28system%28x=0%2Cy=10.5%29%29 , and
system%28x=0%2Cx%2B25y=255%29 --> system%28x=0%2C0%2B25y=255%29 --> system%28x=0%2C25y=255%29 --> system%28x=0%2Cy=255%2F25%29 --> highlight%28system%28x=0%2Cy=10.2%29%29 .

Having the coordinates of two points for each line, all we have to do is
draw the one an only straight line that passes through those two points:
