Chapter 8, Problem 19SGR

To determine

To find: four solutions and write as ordered pairs.

Answer to Problem 19SGR

The four ordered pair solution of the equation $y=x+9$ is: $\left(-1,8\right),\left(0,9\right),\left(1,10\right),\left(2,11\right)$

Explanation of Solution

Given:

Consider the equation: $y=x+9$

Calculation:

Take different value of x and solve for y

Put $x=-1$ inequation.

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

Now, put $x=0$ in equation.

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

Put $x=1$ in equation.

  $\begin{array}{c}y=1+9\\ =10\end{array}$

Put $x=2$ in equation.

  $\begin{array}{c}y=2+9\\ =11\end{array}$

Therefore, the complete table that shows different value of x and y is as follow:

x	y
$-1$	8
0	9
1	10
2	11

Conclusion:

Therefore, the four ordered pair solution of the equation $y=x+9$ is: $\left(-1,8\right),\left(0,9\right),\left(1,10\right),\left(2,11\right)$
