Chapter 9.2, Problem 6GP

To determine

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

Answer to Problem 6GP

The ordered pairs are $\left(-3,4\right)$ , $\left(0,7\right)$ , $\left(3,10\right)$ and $\left(4,11\right)$ .

Explanation of Solution

Given information :

The function is $-x+y=7$ .

Calculation :

Step 1 Choose four value for $x$ and substitute each value into the equation. Choose the value $-3$ ,0,3 and 4.

Step 2 Evaluate the expression to find the value of $y$

Step 3 Write the solutions as ordered pairs.

$x$	$-x+y=7$	$y$	$\left(x,y\right)$
$-3$	$-\left(-3\right)+y=7$	$4$	$\left(-3,4\right)$
0	$0+y=7$	7	$\left(0,7\right)$
3	$-3+y=7$	10	$\left(3,10\right)$
4	$-4+y=7$	11	$\left(4,11\right)$

Hence, the ordered pairs are $\left(-3,4\right)$ , $\left(0,7\right)$ , $\left(3,10\right)$ and $\left(4,11\right)$ .
