Question

which type of graph would best illustrate seasonal changes in temperature over a year?

a. linear

b. constant

c. non - linear

d. vertical line

Explanation:

To determine the best graph for seasonal temperature changes over a year, we analyze each option:

• Option a (Linear): A linear graph implies a constant rate of change, but temperature across seasons (e.g., winter to summer to winter) does not change at a constant linear rate. It rises and falls in a non - uniform way.
• Option b (Constant): A constant graph would show the same temperature throughout the year, which is not true for seasonal changes.
• Option c (Non - linear): Seasonal temperature changes (e.g., cold in winter, warm in summer, and transitions in between) do not follow a straight - line (linear) pattern. The temperature curve over a year has peaks and troughs, so it is non - linear. This type of graph can effectively show the varying rate of temperature change throughout the year.
• Option d (Vertical Line): A vertical line on a graph represents a constant x - value with varying y - values, which is not suitable for showing temperature change over time (a year has a continuous x - axis of time).

Answer:

c. Non - linear
