<u>Sketch A</u>
In sketch A, we have the following observations:
- <em>The arrow faces left (this implies less than)</em>
- <em>The dots on -2 and -5 are closed dots (this implies less than or equal to).</em>

<u>Sketch B</u>
In sketch B, we have the following observations:
- <em>The arrow faces right (this implies greater than)</em>
- <em>The dots on -4 and 3 are closed dots (this implies greater than or equal to).</em>
