Chapter 9.2, Problem 30IP

To determine

To graph : the function by plotting ordered pairs

Explanation of Solution

Given information :

The function is

  $y=-x+5$

Graph :

Find the intercepts

Let $y=0$ to find the $x$ -intercept

  $\begin{array}{l}y=-x+5\\ x=5-y\\ x=5-0\\ x=5\end{array}$

Since $x=5$ when $y=0$ ,graph the ordered pair $\left(5,0\right)$ .

Let $x=0$ to find the $y$ -intercept

  $\begin{array}{l}y=-x+5\\ y=-0+5\\ y=5\end{array}$

Since $y=5$ when $x=0$ ,graph the ordered pair $\left(0,5\right)$ .

Therefore, the graph is obtained as

Interpretation : From the above graph it can be observed that that ordered pairs are $\left(5,0\right)$ and $\left(0,5\right)$ .
