Graphing

Introduction to Coordinate Graphs

By Ms. Shannon

​Why do I need to learn to graph?

• Graphs make information easier to see and understand.

• Graphs show the relationship between two or more things.

  Knowing how to read graphs will help you to understand more about situations that affect your every day life.

Multiple Select

Which of the following are reasons to learn how to read graphs?

• Graphs make information easier to read.

• Graphs make information easier to understand.

• Graphs are never used in everyday life.

​Parts of a Graph

• Title

• Scale​

• X axis

• Y axis​

• Labels for each axis​

• Origin​​

• Coordinate points

Every graph must have a title.

​

The title lets the reader know what the graph is measuring. ​

​

​Title of the Graph

Multiple Choice

According to the title, what is this graph measuring?

• How old Mr. Wayne will be on his birthday (Friday)?

• How many facts there are on the quiz?

• The day number?

• Facts the author got right?

Every coordinate graph has a scale which shows the distance between points on a line.

• One,

  Five

• Five,

• One,

  One

• Five,

  Five

is horizontal....You can find it at the bottom of the graph.

​The X-Axis

is vertical and you can find it on the left side of the graph.

​

​The Y-axis

Multiple Choice

Choose the most accurate answer.

• It doesn't matter which axis is the x and which is the y.

  You can change them whenever.

• The x axis is at the top of the graph and the y axis is usually on the left.

• The x-axis is horizontal and the y-axis is vertical.

• The x-axis is vertical and the y-axis is horizontal.

Multiple Choice

Which of the following is NOT correct.

• The x axis scale shows that the distance between days is one.

• This graph measures both high and low temperatures.

• This graph does not show a relationship between the day and the temperature.

• The x axis is labeled "Days."

What title would you give to this graph?

The origin of the graph is zero on BOTH the x and y axes.

​Origin

Both x and y axes need labels.

The x axis is labeled "Day Number."

The y axis here is labeled "Facts."​
