Independent/Dependent Topic 4 Study Guide

Front

What is an independent variable?

Back

An independent variable is a variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What is a dependent variable?

Back

A dependent variable is the variable that is measured and affected in an experiment. It depends on the independent variable.

Front

How do you write an equation for a relationship?

Back

To write an equation for a relationship, identify the independent variable (x) and the dependent variable (y), then express y in terms of x, often in the form y = mx + b.

Front

What does the slope of a line represent in a graph?

Back

The slope of a line represents the rate of change between the independent variable and the dependent variable.

Front

What is a linear relationship?

Back

A linear relationship is a relationship that can be represented by a straight line on a graph, indicating a constant rate of change.

Front

What is the formula for calculating the total cost of items?

Back

The total cost can be calculated using the formula: Total Cost = Price per Item × Number of Items.

Front

What is a graph?

Back

A graph is a visual representation of data that shows the relationship between two variables.

Front

What does it mean when a graph is increasing?

Back

An increasing graph indicates that as the independent variable increases, the dependent variable also increases.

Front

What does it mean when a graph is decreasing?

Back

A decreasing graph indicates that as the independent variable increases, the dependent variable decreases.

Front

What is a rate of change?

Back

The rate of change is a measure of how much a quantity changes in relation to another quantity, often expressed as a ratio.
