You can put this solution on YOUR website!
solve by graphing::
You need 2 points for each line-------
y=-x+2
If x = 0, y = 2
If x = 2, y = 0
Plot (0,2), (2,0) and draw a line thru them to get::
graph%28400%2C400%2C-10%2C10%2C-10%2C10%2C-x%2B2%2C%28-1%2F2%29x%2B1%29
----
y=-1/2x+1
If x = 0, y = 1
If x = 2, y = 0
Plot (0,1), (2,0) and draw a line thru them to get::
------
Solution:: The lines meet at (2,0)
That is the solution for the system.
