Chapter 9.2, Problem 23IP

To determine

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

Answer to Problem 23IP

The ordered pairs are $\left(-1,-2\right)$ , $\left(0,-3\right)$ , $\left(1,-4\right)$ and $\left(2,-5\right)$ .

Explanation of Solution

Given information :

The function is $x+y=-3$ .

Calculation :

Step 1 Evaluate the equation

  $\begin{array}{l}x+y=-3\\ y=-3-x\end{array}$

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.

$x$	$y=-3-x$	$y$	$\left(x,y\right)$
$-1$	$y=-3-\left(-1\right)$	$-2$	$\left(-1,-2\right)$
0	$y=-3-0$	$-3$	$\left(0,-3\right)$
1	$y=-3-1$	$-4$	$\left(1,-4\right)$
2	$y=-3-2$	$-5$	$\left(2,-5\right)$

Hence, the ordered pairs are $\left(-1,-2\right)$ , $\left(0,-3\right)$ , $\left(1,-4\right)$ and $\left(2,-5\right)$ .
