Exercise 33 Page 160

Substituting values from the domain will give the corresponding values from the range.

Table:

x	y
-2	10
0	8
2	6

Graph:

Practice makes perfect

Let's graph using a table. First select some arbitrary values from the domain, then substitute them for x in the given equation. Solving for y will give us the corresponding values from the range.

x	y-8=- x	Simplify
-2	y-8=-(-2)	y= 10
0	y-8=-(0)	y= 8
2	y-8=-(2)	y= 6

Using these x and y values as ( x, y) coordinate pairs, we can plot the points. Connecting these points will give us the graph of the equation.
