Write whether each of these systems of equations has a common solution or not. Explain.
y = -x+2 y = 2x+1

You can put this solution on YOUR website!
Write whether each of these systems of equations has a common solution or not. Explain.
y = -x+2
slope = -1
--------------
y = 2x+1
slope = 2
---------------
Since the slopes are different there is a common solution point.
----------------
Slopes different means the lines are not parallel.
------------------
