Question 22836: PLEASE HELP ME SOLVE THE SYSTEM OF EQATIONS BY GRAPHING AND CHECK
X - Y = 3
X + Y = 1
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! Solve the 1st equation for "Y" as follows:
Y = X-3. Now plot a couple of points, like
(0,-3) and (3,0) and draw the line.
Then solve the 2nd equation for Y as follows:
Y = -X+1. Plot a couple of points for this
equation, such as ((0,1) and (1,0), and draw
that line.
Find the point where the two lines meet. The
X and Y value of that point give you the solution.
Cheers,
Stan H.
