Exercise 23 Page 402

Choose some values of x and substitute them into the rule.

Practice makes perfect

We want to graph the rule y = 2x - 6. To do this, we can choose some values of x and substitute them into the rule, one at a time.

x	2x - 6	y
0	2( 0) - 6	- 6
1	2( 1) - 6	- 4
2	2( 2) - 6	- 2
3	2( 3) - 6	0

Let's graph each pair of (x,y) as a point on a coordinate plane.

Finally, we can connect the points with a line.
