Answer:
Graph is attached below
Explanation:

To graph the inequality , we replace < symbol by = sign

Now we graph the given equation by making a table
x y=3x+1
-1 -2
0 1
1 4
Graph all the points (-1,-2) (0,1) (1,4) and make a line
Now we do shading using test point (0,0)

True
So we shade the region that has test point (0,0)
the graph is attached below
