You can put this solution on YOUR website!
Start with the graph of y = 4x+5



Now only draw the portion that makes x%3C=0 true (so everything to the left of 0 and we include 0 itself).



Notice how I erased the portion to the right of x = 0. There is a closed circle at x = 0.

We can see the range is y%3C=5. In interval notation, the range is (-\infty,5]
