Systems
of Equations: Graphing
Solve by graphing:
x + 2y = 4
By intercepts:
(0, 2)
(4, 0)
y = –1/2x + 1
By slope-intercept:
m = –1/2
b = 1
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 are parallel.
There is no solution to the system.
The system is inconsistent.
