Systems
of Equations: Graphing
Solve by graphing:
–2x + 2y = 4
By intercepts:
(0, 2)
(–2, 0)
y = x + 2
By slope-intercept:
m = 1
b = 2
A solution
of the system will be a point that works in both equations.
This would be a point
on both lines.
What can we
say about a solution of the system?
The lines coincide.
There are infinitely
many solutions to the system.
The system is dependent.
