Solve by graphing

(1) x + y = 6

(2) 4x - y = 4

This is one question.

For this one, solve each equation for y.

(1) y = -x + 6

(2) y = 4x - 4

Now set up a table of arbitrary x-values for each equation and find the corresponding y-value. Then graph the points, draw a straight line through the points and see if you can determine where the two lines intersect. From the tables, we can see...

Code:

(1) y = -x + 6 (2) y = 4x - 4
________ _________
x | y x | y
----------- ------------
0 | 6 0 | -4
1 | 5 1 | 0
2 | 4 2 | 4
3 | 3 3 | 8

Now you can see from the table that the third entries in each table are identical. Guess what that means?
