To solve the question, let us analyze the problem step-by-step:

Information from the table:

1. Morgantown: $7^\circ$ below $0$, represented as $-7$.
2. Charlotte: $6^\circ$ above $0$, represented as $+6$.
3. Huntsville: $4^\circ$ above $0$, represented as $+4$.
4. Bluefield: $8^\circ$ below $0$, represented as $-8$.

Instructions:

• On a vertical number line, higher numbers are plotted above lower numbers.
• Therefore:
  • Morgantown ($-7$) should be plotted above the point representing Bluefield ($-8$).
  • Huntsville ($+4$) should be plotted below the point representing Charlotte ($+6$).

Final Answer:

1. Morgantown's lowest recorded temperature should be plotted above the point representing Bluefield's lowest recorded temperature.
2. Huntsville's lowest recorded temperature should be plotted below the point representing Charlotte's lowest recorded temperature.

Tip:

When plotting temperatures on a number line, always convert all descriptions (e.g., "below 0") into numerical values first to avoid confusion.
