<PRE><B>Question 294042</B>
solve the system of equation by graphing 
                y=2x-1
                y=-x+5
-------------
These are 2 straight lines. Graphing a straight line requires only 2 points.
Pick 2 values for x and find y.  Plot the points. Draw a line thru them.
Do the same for the 2nd eqn.
Where they intersect is the solution.
