4x-y Greather than or equal too 8
Graph the inequality.
-----
Solve for "y":
4x -y >= 8
y <= 4x -8
-----
1st: Graph the boundary; y = 4x-8
You need 2 points:
If x = 0, y = -8
If x = 2, y = 0
---
Plot the 2 points (0,-8) and (2,0) and draw a solid line thru them.
-------
2nd: Graph the inequality:
Since you want y Less then 4x-8, shade the half-plane BELOW
the boundary line.
