Chapter 8.3, Problem 21PPS

To determine

To calculate: To find four solutions for the equation and write the solutions as ordered pairs

Answer to Problem 21PPS

Four solutions for the equation is $\left(0,-4\right),\left(1,-7\right),\left(2,-10\right),\left(3,-13\right)$

Explanation of Solution

Given information: Equation is $y=-3x-4$

Calculation:

Equation is given as

  $y=-3x-4$

When $x=0$

  $\begin{array}{l}y=-3\left(0\right)-4\\ y=0-4\\ y=-4\end{array}$

When $x=1$

  $\begin{array}{l}y=-3\left(1\right)-4\\ y=-3-4\\ y=-7\end{array}$

When $x=2$

  $\begin{array}{l}y=-3\left(2\right)-4\\ y=-6-4\\ y=-10\end{array}$

When $x=3$

  $\begin{array}{l}y=-3\left(3\right)-4\\ y=-9-4\\ y=-13\end{array}$

Thus, four solutions are $\left(0,-4\right),\left(1,-7\right),\left(2,-10\right),\left(3,-13\right)$
