First graph the line,2x-y=12
y=2x-12
.
.
.
graph%28300%2C300%2C-10%2C10%2C-10%2C10%2C2x-12%29
.
.
.
Now choose a point not on the line.
(0,0) is a convenient choice.
Test the inequality.
If the inequality is satisfied, shade the region containing (0,0).
If not, shade the region that does not contain (0,0).
2x-y%3E=12
2%280%29-0%3E=12
0%3E=12
False, shade the region not containing (0,0)
