First you would have to solve it. 15+x less than or equal too 0. Subtract 15 on both sides of the inequality sign. So x=0. Now you would make your number line with only 3 dashes. Then the number in the middle would be 0 then to the right it would 1 and too the left it would be a -1. So your going to point to all numbers less than 0. So point an arrow to the -1. Then do a closed circle on the dash in the middle over the 0 because it is less than or equal too not just less than. And that is how you graph your equation!!
