12-18 Independent Practice (On-Level)

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, depending on the independent variable.

Front

How do you identify the independent variable in a table of values?

Back

The independent variable is usually found in the first column of a table, as it is the variable that you manipulate.

Front

What does a linear relationship look like on a graph?

Back

A linear relationship on a graph appears as a straight line, indicating a constant rate of change between the variables.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run (change in y over change in x).

Front

How can you determine the equation of a line from a graph?

Back

You can determine the equation of a line by identifying the slope and the y-intercept from the graph.

Front

What is the y-intercept?

Back

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

Front

What does it mean for two variables to be directly proportional?

Back

Two variables are directly proportional if they increase or decrease together at a constant rate, represented by the equation y = kx, where k is a constant.

Front

What is a function?

Back

A function is a relationship between two sets of values where each input (x) has exactly one output (y).

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, often using patterns or differences.
