GG easy
y<19, that means that we include all numbers greater than 19 but not including 19
so go to the graph and go up along the y axis 19 units and draw a horizontal dotted line, then shade below that
looks summat like thar attachment

Graph y < 19
When you see these kinds of graphing just keep in mine that it will be a line with a slope of 0 that runs across the point on the x axis of in this case 19.
Hope This Helps :)
