Independent and Dependent Variable Math

Front

What is an ordered pair in the context of a coordinate plane?

Back

An ordered pair is a pair of numbers used to locate a point on the coordinate plane, typically written in the form (x, y).

Front

In a relationship between two variables, what is the independent variable?

Back

The independent variable is the variable that is manipulated or changed in an experiment to observe its effect on the dependent variable.

Front

Identify the independent variable in the following scenario: The number of students, s, ahead of you in the lunch line and the time, t, it takes you to get lunch.

Back

s, the number of students ahead of you.

Front

Identify the independent variable in the following scenario: The amount of time, t, to finish a race and the number of laps, l, around a track.

Back

l, the number of laps.

Front

Identify the independent variable in the following scenario: The length, l, of a pencil and the number of times, t, it has been sharpened.

Back

t, the number of times sharpened.

Front

What is the dependent variable in a relationship between two variables?

Back

The dependent variable is the variable that is measured or observed in response to changes in the independent variable.

Front

What quadrant would you find the ordered pair (9, 0)?

Back

The ordered pair (9, 0) is located on the x-axis.

Front

What is the significance of the x-axis in a coordinate plane?

Back

The x-axis is the horizontal axis in a coordinate plane where the y-coordinate is zero.

Front

What is the significance of the y-axis in a coordinate plane?

Back

The y-axis is the vertical axis in a coordinate plane where the x-coordinate is zero.

Front

How do you determine the location of a point given its ordered pair?

Back

To determine the location of a point given its ordered pair (x, y), move x units along the x-axis and y units along the y-axis.
