(-1,3)

#### Explanation:

To solve the system $3 x - y = - 6$ and $x + y = 2$ by graphing, put the equations in slope intercept form:
$3 x - y = - 6$
$- y = - 3 x - 6$
$y = 3 x + 6$
and
$x + y = 2$
$y = - x + 2$
Then graph the two equations on a coordinate plane. The intersection of the lines will be the solution: (-1,3)
