First graph the line, 2x=-8y
y=-x%2F4

.
graph%28300%2C300%2C-10%2C10%2C-10%2C10%2C-4x%29
Now choose a point not on the line and test the inequality.
If the inequality is true, shade the region containing the test point.
If not, shade the region not containing the test point.
Let choose (6,0).
2%280%29%3C-8%286%29
0%3C-48
False, so shade the region not containing (6,0).
