You can put this solution on YOUR website!
First graph the line
y=3x%2B7
When x=0
y=3%280%29%2B7=7
(0,7)
When x=-2
y=3%28-2%29%2B7=-6%2B7=1
(-2,1)

Now choose a point not on the line.
(0,0) is convenient.
Test the inequality.
If it's true, shade the region containing (0,0).
If it's false, shade the other region.
y%3C3x%2B7
0%3C3%280%29%2B7
0%3C7
True.
