coordinate graph

a display of data made up of points that are related to the independent and dependent variables



coordinate pair

The numbers on the X and Y axis are called a 'coordinate pair'
For example, if y = 3 when x = 2, then (2,3) is a coordinate pair. 


dependent variable

The 'jumping jacks' in the jumping jack activity are an example of a dependent variable.

the number on the vertical axis


distance

you find 'distance' when you multiply time by rate of speed
D= miles per hour X time 


equation

a rule that has a variable like C=d x pi that always has an equal sign

y=2x or y = 4x + 2


profit

You find profit when you subtract cost (or expenses) from the income



independent variable

TIME is often an example of an independent variable.

the number on the horizontal axis


pattern

On a graph, we notice a ________ by looking at how the data changes.



relationship

How one variable affects another variable is called a RELATIONSHIP.

Pretend that I am the independent variable in my relationship with you, and YOU are the dependent variable. If I am not kind to you, we have a BAD relationship. If I respectful to you, we have a GOOD relationship.


rule

a rule tells you how to find the value of a variable.



scale

numbers on the x and y axis represent the 'scale'



table

When two or more variables are recorded on a vertical/horizontal list is called a TABLE.



variable

a quantity (often a number) that can change.
For example, when y= 3x or when y=3x + 2, 'x' and 'y' are variables in both number sentences. 


Xaxis

The independent variable always goes on the coordinate grid's horizontal line. The name for this horizontal line is called the Xaxis.



Yaxis

The dependent variable always goes on the coordinate grid's vertical line. This line is called the Yaxis.
