How do I solve each system by graphing?
You have to graph the boundaries, which are ALWAYS an equality.
---
2x-y(less than equal to)2
Solve for "y":
y > = 2x-2
Graph the boundary y = 2x-2
Shade the half-plane ABOVE the boudary because
you want y to be GREATER than 2x-2.
--------
y(greater than equal to)4
y >= 4
Graph the boundary y = 4
Shade the half-plane ABOVE the boundary.
--------
The solution for the system is the intersection
of the two graphs.
