# How do you solve by graphing 3x - y = -6 and x + y = 2?

May 21, 2015

Determine two points for each of the given equations which you can use to draw the straight lines each represents.

The simplest pairs are probably the x and y intercepts
$3 x - y = - 6$

$\left(0 , 6\right)$
$\left(- 2 , 0\right)$

$x + y = 2$

$\left(0 , 2\right)$
$\left(2 , 0\right)$

From the graph we can see that the line intersect at $\left(- 1 , 3\right)$
