Question 922545
{{{x+y>-8}}}
{{{y>-x-8}}}
First, plot the line,
{{{y=-x-8}}}
.
.
{{{graph(300,300,-10,10,-10,10,-x-8)}}}
.
.
Now choose a point not on the line.
(0,0) is convenient.
Test the inequality. 
If true, (0,0) is in the solution region.
If not, shade the region not containing (0,0).
{{{0+0>-8}}}
{{{0>-8}}}
True.
{{{graph(300,300,-10,10,-10,10,y>-x-8)}}}
