The graph of the inequality 3x + y > -7 is in the image at the end.
How to graph the inequality?
Here we have the inequality:
3x + y > -7
Isolating y we will get:
y > -3x - 7
To graph this, graph the line:
y = -3x - 7
With a dashed line (because the points in the line are not solutions). Then shade the region above the line (because y is larger than the line)
The graph of the inequality is in the image below.
