Chapter 8.3, Problem 33PPS

To determine

To calculate: To graph the equation $x-y=1$

Answer to Problem 33PPS

Graph for equation is plotted.

Explanation of Solution

Given information: Equation is $x-y=1$

Calculation:

Equation is given as

  $x-y=1$

Rewrite the above equation as follows:

  $y=x-1$

When $x=0$

  $\begin{array}{l}y=0-1\\ y=-1\end{array}$

When $x=1$

  $\begin{array}{l}y=1-1\\ y=0\end{array}$

When $x=2$

  $\begin{array}{l}y=2-1\\ y=1\end{array}$

Thus, four solutions are $\left(0,-1\right),\left(1,0\right),\left(2,1\right)$
