coordinate system
What is a coordinate system?
Is the intersection of two number lines, the horizontal azis and the vertical axis.
The vertical axis is also called…
y-axis

Is a set of numbers, or coordinates, written in the form (x,y)
The x value is called…
the x-coordinate
the x-coordinate corresponds to the
x-axis
The y value is called…
the y-coordinate
the y-coordinate corresponds to the
y-axis
What is the independent variable?
It is not affected by the other variables and it is usually situauted in the x-aixs.
What is the dependent variable?
It is affected by the other variables and it is usually situated in y-axis.
What is the origin?
Is the point were the axis intersect.
A set of order pairs is called…
a relation
The set of the first numbers of the ordered pairs are called
the domain
what is the domain
is the set of the first numbers of the ordered pairs.
The domain contains values of the
independent variable
The set of the second numbers of the ordered pairs are called
the range
What is the range?
Is the set of the second numbers of the ordered pairs.
The range contains the values of the
dependent variable
What is the relation?
Is the set of order pairs
