Solving Systems of Equations by Graphing
Solve the following system by graphing:
y = 2x + 6
y = -1x + 0
y = 2x + 6
The intersection of both lines is the
solution. This solution is expressed
as a coordinate pair.
(-2, 2)
y = -1x + 0
There are two lines here, one on
top of the other.
Solution: Infinite
Parallel lines have no solution!
