Question 81246
2x + y > -4
:
y > -2x - 4; subtracted 2x from both sides
:
Plot table; substitute for x = -3, x = 0, x = +2 and solve for y
:
 x | y
--------
-3 | 2
 0 |-4
+2 |-8
:
Plot these coordinates, your graph should look like this:
{{{ graph( 300, 200, -6, 5, -10, 10, -2x - 4) }}}
:
Remember we have the > sign, the feasibility region will be above the graph line
(not at). This can be indicated by a dashed line instead of a solid line.
