Solve the system by graphing.
3x + y = –1
9x + 3y = –3
----------------
Put both equations in slope-intercept form.
-----------------
y = -3x-1
y = -3x-1
---------------------
Graph:

================
Solution: Since the two equations are the same every point
on the line y = -3x-1 is a solution for the system.
================
