I am having problems understanding how to graph the inequality for the following problem. xis greater than or equal to -2y and x-3y<6. I have to graph the compound inequality but i don't understand this.
--------------
x >=-2y
x-3y<6
-------------
Solve each for y as follows:
y>= -(1/2)x
y>(1/3)x-2
---------------
Graph the EQUALITY of eqch equation:
y=(-1/2)x
Use points (0,0) and (2,-1)
Draw a solid line thru these points.
Shade the half-plane ABOVE the line to graph y>-(1/2)x
---------------
Graph the EQUALITY of the 2nd equation:
y=(1/3)x-2
Use points (0,-2) and (3,-1)
Draw a dashed or dotted line thru these points.
Shade the half-plane ABOVE the dotted line to graph y>(1/3)x-2
