Stuck on PTE Line Graphs? The 40-Second Trend Expression Rescue Guide (2026)

Many practice PTE Describe Image with a lingering anxiety: the moment a line graph appears, you panic. With multiple lines, your eyes dart around, the 25 seconds disappear, and once you start speaking, you feel compelled to list every single number.

A line graph only requires explaining three things clearly: what is being compared, the overall direction, and which change is most obvious.

Focus on the Graph's Main Line during the 25-Second Preparation

Pearson allows 25 seconds to prepare and 40 seconds to answer for Describe Image. In the first 5 seconds, look at the title, x-axis, and y-axis to identify the subject, time, and units. Then, determine if each line is rising, falling, stable, or fluctuating. Finally, find the highest point, lowest point, and one obvious gap.

Writing keywords in your notes is enough: topic / overall rise / A peak 80 / B stable / A above B. These phrases help you maintain your speaking order without writing full sentences during the preparation time.

Set the Context with One Opening Sentence

You can describe it in your own words: The line graph shows the changes in ... from ... to .... When the title is long, just grab the subject and time. The first sentence clarifies the years, subject, and indicator; details follow later.

State the Overall Trend: Direction First, Then Extent

Reporting only numbers without explaining changes sounds like reading coordinates. For increases, use increased steadily or rose sharply; for decreases, use declined gradually or fell significantly. For constant oscillation, use fluctuated; for long periods of stationarity, use remained stable.

Use Numbers to Anchor Peaks and Lows

For the peak, say reached a peak of; for the lowest point, say hit a low of. When numbers are unclear, use around 70 percent or just over 50; don't let a single digit stop your entire sentence.

Example: The figure for A rose from about 30 to a peak of nearly 80. This sentence covers the starting point, end point, and amplitude, making it more useful than listing five or six years. Ensure units for percentages, amounts, and populations are included.

When Comparing Two Lines, Focus on One Relationship

When two or three lines appear together, describe the main change of one line first, then supplement how it relates to the other line. If it remains constantly higher or lower, say A remained higher than B throughout the period. If the gap narrows, say The gap between them narrowed over time. If they cross, say A overtook B after 2016.

If the directions differ, While A continued to rise, B declined slightly. completes the comparison.

Structure Your 40-Second Answer in Four Sentences

The first sentence identifies the theme and time; the second states the overall trend; the third highlights a high point or major change with a number; the fourth provides a comparison or conclusion: Overall, A showed the strongest growth, while B changed only slightly.

You can link them with while, whereas, or compared with. This usually extends to 30 to 40 seconds. Pearson’s recommendation is also to focus on key information; you don't need to cover every tiny detail.

Practice by Analyzing Trends and Comparisons

Practice 5 images daily: Write 5 keywords in 25 seconds for each, then record a 40-second response. Listen back to check the theme, overall trend, one number, one comparison, pronunciation, and pauses. If you get stuck on a city name, use this category or the figure to bridge the gap; don't let silence break your sentence flow.
