Chapter 6.1, Problem 6CB

To determine

To solve: given system of linear equation by graphing.

Answer to Problem 6CB

  $x=4\text{ and }y=-5$

Explanation of Solution

Given information: a system of linear equation is given as follows-

  $\begin{array}{l}y=2x-13\\ y=x-9\end{array}$

$y=2x-13$
$x$	4	5
$y$	-5	-3

$y=x-9$
$x$	4	5
$y$	-5	-4
