Chapter 9.2, Problem 24IP

To determine

To find : four solution of the function and write the solution as ordered pairs.

Answer to Problem 24IP

The ordered pairs are $\left(-1,11\right)$ , $\left(0,9\right)$ , $\left(1,7\right)$ and $\left(2,5\right)$ .

Explanation of Solution

Given information :

The function is $2x+y=9$ .

Calculation :

Step 1 Evaluate the equation

  $\begin{array}{l}2x+y=9\\ y=9-2x\end{array}$

Step 2 Choose four value for $x$ and substitute each value into the equation. Choose the value $-1$ ,0,1 and 2.

Step 3Evaluate the expression to find the value of $y$

Step 4Write the solutions as ordered pairs.

$x$	$y=9-2x$	$y$	$\left(x,y\right)$
$-1$	$y=9-2\left(-1\right)$	$11$	$\left(-1,11\right)$
0	$y=9-2\left(0\right)$	$9$	$\left(0,9\right)$
1	$y=9-2\left(1\right)$	$7$	$\left(1,7\right)$
2	$y=9-2\left(2\right)$	$5$	$\left(2,5\right)$

Hence, the ordered pairs are $\left(-1,11\right)$ , $\left(0,9\right)$ , $\left(1,7\right)$ and $\left(2,5\right)$ .
