Tables, Graphs Equations

Front

What is the independent variable?

Back

The independent variable is the variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable. In the context of tables and graphs, it is often plotted on the x-axis.

Front

What is the dependent variable?

Back

The dependent variable is the variable that is measured and affected in an experiment. It is plotted on the y-axis in graphs.

Front

What does the x-axis represent in a graph?

Back

The x-axis represents the independent variable in a graph.

Front

What does the y-axis represent in a graph?

Back

The y-axis represents the dependent variable in a graph.

Front

How do you write an equation from a table of values?

Back

To write an equation from a table, identify the relationship between the independent and dependent variables, and express it in the form of y = mx + b, where m is the slope and b is the y-intercept.

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed. It can be written in the form y = mx + b.

Front

What does the slope of a line represent?

Back

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

Front

What does the y-intercept represent in a graph?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of the dependent variable when the independent variable is zero.

Front

How can you determine the slope from a graph?

Back

The slope can be determined by selecting two points on the line, calculating the rise (change in y) over the run (change in x).

Front

What is a coordinate point?

Back

A coordinate point is a pair of numbers that define a position on a graph, written in the form (x, y).
