Please Graph the following inequality x - y ≤ 2
put this solution on YOUR website!
In order to graph
, we need to graph the
(just replace the inequality sign with an equal sign).
So lets graph the line
(note: if you need help with graphing, check out this
Now lets pick a test point, say (0,0). Any point will work, (just make sure the point doesn't lie on the line) but this point is the easiest to work with. Now evaluate the inequality
with the test point
Substitute (0,0) into the inequality
(note: for some reason, some of the following images do not display correctly in Internet Explorer. So I recommend the use of
to see these images.)
Since this inequality is true, we simply shade the entire region that contains (0,0)
with the boundary (which is the line
in red) and the shaded region (in green)
