How do you graph #y<2#?
Draw a dotted line along the graph y-axis corresponding to 2, parallel to the x-axis. Then shade all of the area under it. That will be all of the values of y on the graph that are less than 2.
The dotted line represents the limit – going up to 2, but not including it. The shading means that all of the values in that area meet the criteria. The line extends to infinity parallel to the x-axis because we didn’t specify any parameter for an x term.
