Chapter 4.4, Problem 3LC

To determine

To graph: The equation $y=9-x$ on the graph paper.

Explanation of Solution

Given:

The equation is $y=9-x$ .

Calculation:

Substitute $x=0$ in the given equation to obtain the value of $y$ as follows:

  $\begin{array}{c}y=9-0\\ =9\end{array}$

Substitute $x=1$ in the given equation to obtain the value of $y$ as follows:

  $\begin{array}{c}y=9-1\\ =8\end{array}$

Substitute $x=2$ in the given equation to obtain the value of $y$ as follows:

  $\begin{array}{c}y=9-2\\ =7\end{array}$

Substitute the obtained values in the table given below.

$x$	$y$
0	9
1	8
2	7

Plot the points and join them to obtain the graph as follows:
