  $y=8x$

Answer to Problem 16PPS

The four solutions as ordered pairs are $\left(-1,-8\right)$ , $\left(0,0\right)$ , $\left(1,8\right)$ and $\left(2,16\right)$ .

Explanation of Solution

Given information:

Equation is $y=8x$

Formula Used:

To solve an equation with multiple variables, we need to consider some random values for one of the variables and solve for the other one to find the ordered pair.

Calculation:

Given equation is $y=8x$

Using the above explanation, we have -

Let the value of $x$ be $-1$ , substituting the value of $x$ in the above equation, we have:

  $y=8\left(-1\right)$

Solving the above equation, we have :

  $y=-8$

Thus, the first ordered pair is $\left(-1,-8\right)$ .

Using the same approach to find the other ordered pairs −

Let the value of $x$ be $0$ , substituting the value of $x$ in the above equation, we have:

  $y=8\left(0\right)$

Solving the above equation, we have :

  $y=0$

Thus, the second ordered pair is $\left(0,0\right)$ .

Let the value of $x$ be $1$ , substituting the value of $x$ in the above equation, we have:

  $y=8\left(1\right)$

Solving the above equation, we have :

  $y=8$

Thus, the third ordered pair is $\left(1,8\right)$ .

Let the value of $x$ be $2$ , substituting the value of $x$ in the above equation, we have:

  $y=8\left(2\right)$

Solving the above equation, we have :

  $y=16$

Thus, the fourth ordered pair is $\left(2,16\right)$ .

Thus, the four ordered pairs are $\left(-1,-8\right)$ , $\left(0,0\right)$ , $\left(1,8\right)$ and $\left(2,16\right)$ .
