Line graph worksheet for Pre-Algebra

A line graph shows one thing measured again and again over time. The height of each point is the value at that time, and the steepness of the line between two points is how fast it changed.

Also taught in Statistics, at its own level and with its own examples.

How to do these

A plant is 10 cm in week 2 and 25 cm in week 4. By how many centimeters did it grow?

  1. Read the two heights: 10 and 25.
  2. The change is 25 minus 10.

The answer is 15.

Where students go wrong

Taking the highest point as the greatest increase. The greatest increase is the biggest rise between two neighboring points, wherever it happens on the graph.

Also called line graph, line graphs, reading line graphs or interpreting line graphs.

What you can put on this worksheet

Read one point
How tall was the plant, in centimeters, in week 2? — plant height: a line graph of centimeters from wk 1 to wk 5 → 8
The change between two points
By how many centimeters did the plant's height increase from week 4 to week 5? — plant height: a line graph of centimeters from wk 1 to wk 5 → 2
The greatest increase
What was the greatest increase from one week to the next? — plant height: a line graph of centimeters from wk 1 to wk 5 → 4
The mean of the values
What was the mean number of visitors per day? — library visitors: a line graph of visitors from mon to fri → 36
Percent change
By what percent did the number of visitors decrease from Thursday to Friday? — library visitors: a line graph of visitors from mon to fri → 25%
Median, range and mode
Find the range of the data in the graph. — visitors: a line graph of visitors from jan to jun → 30
Make a line graph from a table
Make a line graph of the cups of lemonade a stand sold each day.
Day12345Cups sold62222 — lemonade sales: a line graph of cups sold from day 1 to day 5 → (1,6), (2,2), (3,2), (4,2), (5,2)

Questions about these worksheets

Yes. Every line graph sheet is free to print and free to download as a PDF. There is no account to make, no email to hand over and no limit on how many you take.

Yes. The answer key prints on a second page, and you can choose whether it shows each question beside its answer or just the answers in a list.

Yes. Print straight from the page, or download the PDF and print that. The sheet is laid out for paper rather than squeezed off a screen, so there is room to work under each question, and the answer key comes out on its own page.

Pre-Algebra is usually taken around 7th or 8th grade, though schools vary and plenty of students meet it earlier or later. Pick the difficulty rather than the grade: the easy level suits a first lesson on it, the hard level suits review before a test.

Yes, as many as you like. The questions are built fresh each time rather than picked from a fixed set of files, so pressing Generate gives a new sheet. That is what you want for a second class, a retake, or two students sitting next to each other.

That is the closest comparison, and Kuta Software is good software. It is also paid software you install on a computer. These worksheets run in a browser tab for free, with no account and nothing to install. Like Kuta, the line graph questions are generated when you ask for them rather than pulled from a fixed set of files, so two classes never get the same sheet, and the answer key comes with it.

Yes. There are three levels, and you can tick more than one for a sheet that mixes them, in which case the questions come out easiest first. The harder levels are not just larger numbers: they ask for something the easy ones do not.

You pick from 7: read one point, the change between two points, the greatest increase, the mean of the values, percent change, median, range and mode and make a line graph from a table. Tick as many as you want and set how many of each, or let it spread them evenly.

Taking the highest point as the greatest increase. The greatest increase is the biggest rise between two neighboring points, wherever it happens on the graph.
