: Comparing Methods:
Solve the linear system using all three methods on page 418.

3x - y = 3
-x + y = 3

I have the answer (3,6)
But I don't understand how to graph it.
Which is the first method to use, graphing. This question is from textbook

3x - y = 3
-x + y = 3
-----------
Solve each equation for "y":
y = 3x-3
y = x+3
--------------
Graph y=3x-3
Let x=0,then y=-3, giving you point (0,-3)
Let x=1, then y= 0, giving you point (1,0)
Plot those two points and draw a line thru them.
---------------------
Graph y = x+3
Let x=0, then y = 3 giving you point (0,3)
Let x=1, then y = 4 giving you point (1,4)
Plot those two points and draw a line thru them.
---------------------
