In a line graph, the trend from 2018 to 2020 shows increasing values; what does that indicate about the data?

• A. The data remains constant across years.
• B. Data fluctuates with no clear direction.
• C. A rising trend or growth over the period.
• D. A decline over the period.

Answer: (C)

Line graphs show how values change over time, and the slope of the line reveals the direction of those changes. If the values rise from 2018 to 2020, the line moves upward, signaling a rising trend or growth over that period. This interpretation fits best because it captures the overall upward movement across the years, rather than suggesting no change, random ups and downs, or a decline. A flat line would mean no change, fluctuations with no clear direction would show a mix of ups and downs, and a downward slope would indicate a decrease.
