Chapter 3 Linear Systems and Matrices - Investigating Algebra Activity - 2.1 Solving Linear Systems Using Tables - Page 152: 1

$x=-1$ $y=3$

To solve the equation, we will use the table function of a graphing calculator. Input both of the equations as $y_1$ and $y_2$ and look for an $x$ value where both $y_1$ and $y_2$ are the same. $y_1=2x+5$ $y_2=-x+2$ As the output shows, the answer is $x=-1$, $y=3$
