Firstly you have to turn it into an equation: Y=3x+1 to find the coordinates

at y axis x=0

y=3(0)+1

y=1

find the pair (0,1) on your graph

at x axis y =0

(0)=3x+1

-1=3x

-1/3=x

find the pair (-1/3,0) on your graph

join those 2 pairs with a dotted line (because it is less)

then you have to shade the part that this inequality represents. And since y is less than 3x+1 you shade the space ABOVE your dotted line .

hope this has helped!
