Answer:

(x, y) = (-4, -6)

Explanation:

For graphing by hand, it can be convenient to put the equations in slope-intercept form. Multiplying the first equation by -2 gives ...

y = -x -10

The second equation is already in slope-intercept form.

These equations tell you ...

y = -x -10 . . . the slope is -1 and the y-intercept is -10. It goes up to the left from -10 on the y-axis

y = 2x +2 . . . the slope is 2 and the y-intercept is 2. It goes down to the left from +2 on the y-axis.

The solution to the system is (-4, -6).
