Chapter 9.2, Problem 22IP

To determine

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

Answer to Problem 22IP

The ordered pairs are $\left(-1,-1\right)$ , $\left(0,-4\right)$ , $\left(1,-7\right)$ and $\left(2,-10\right)$ .

Explanation of Solution

Given information :

The function is $y=-3x-4$ .

Calculation :

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

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

Step 3 Write the solutions as ordered pairs.

$x$	$y=-3x-4$	$y$	$\left(x,y\right)$
$-1$	$y=-3\left(-1\right)-4$	$-1$	$\left(-1,-1\right)$
0	$y=-3\left(0\right)-4$	$-4$	$\left(0,-4\right)$
1	$y=-3\left(1\right)-4$	$-7$	$\left(1,-7\right)$
2	$y=-3\left(2\right)-4$	$-10$	$\left(2,-10\right)$

Hence, the ordered pairs are $\left(-1,-1\right)$ , $\left(0,-4\right)$ , $\left(1,-7\right)$ and $\left(2,-10\right)$ .
