A solid line is used to define the inequality.

#y <= x+3#

Explanation:

Treat this in exactly the same way as the equation of a straight line.

However, instead of the solution being only along the line itself, any point below the line will also be a solution for the inequality.

#y -x <= 3 " "rArr y <= x+3#

graph{y <= x+3 [-7.33, 12.67, -1.24, 8.76]}
