Question 565881: on the grid solve the following system of inequalities.
2x + y < -4
x - y >_ 1 (the drop bar should be under the > sign. i dont know how to type that on the computer.)
i really need help with this problem. thank you all.i have gotten it wrong 3 times.
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! 2x + y < -4
x - y >= 1
----
Rearrange and graph each inequality:
y < -2x-4
Graph the boundary as a dashed line
thru (0,-4) and (-1,-2)
---
Shade the half-plane BELOW the boundary.
=================================================
Rearrange and graph each inequality:
y <= x - 1
Graph the boundary as a solid line
thru (0,-1) and (1,0)
----
Shade the half-plane BELOW the boundary.
-----------
The solution for the system is the intersection
of the 2 graphs.
