# How do you solve the system x+y=4 and x - y = -6 by graphing?

Dec 6, 2015

$\left(- 1 , 5\right)$

#### Explanation:

Graph the $2$ equations.

(It may be easier to think about them in $y = m x + b$ form. These can be written as $y = - x + 4$ and $y = x + 6$.)

Notice that they intersect at the point $\left(- 1 , 5\right)$.

This is the only point which satisfies both equations.
