Question 67122
graph the equation 4x+y >_ 4
:
4x + y >= 4
:
y >= -4x + 4
:
Choose some values for x and find y
An example x = -2: 
y = -4(-2) + 4
y = + 8 + 4
y = 12
;  
Plot the graph using following values:
 x|y
-----
-2|12
 0| 4
+3| -8 
:
It should look like this:
{{{ graph( 300, 200, -6, 6, -16, 16, -4x + 4) }}}
:
Remember we had y >= -4x +4, which means the area of interest is at or above
the line on the graph
