how do you graph . 4x + y ≥ 4 and 3x -4y < 12
----------
You solve each for y:
y>=-4x+4
y<(3/4)x+3
--------------
You then graph the EQualities:
If y=-4x+4 use points (0,4) and (1,0) to draw the solid line.
If y<(3/4)x+3 use points (0,1) and (4,4) to draw a dashed line.
These lines are the boundary lines of the half-planes which are
the graph of each INequality.
--------------
Since you want y>-4x+4 you darken the half-plane above the solid line y=-4x=4
------------
Since you wnat y<(3/4)x+3 you darken the half-plane below the dashed line
y=(3/4)x+3
-----------
I can't tell from your post if you are asking to graph two separate problems
or is you want the AND (intersection) of the two graphs.
You will have to decide.
Cheers,
