Congratulations, you've done the algebra correctly!
Now, plot the points in the cartesian plane to obtain the line.
When we deal with "greater than" or "less than" inequalitites, we draw a dashed line - - - - to connect the points. Then shade the area above the line if it's "greater than"; or below the line if it's "less than".
Similarly, when we deal with "greater than or equal to" or "less than or equal to" inequalitites, we draw a solid line to connect the points. Then shade the area above the line if it's "greater than or equal to"; or below the line if it's "less than or equal to".
Done!
