A1-Unit 3 Linear Functions Review

Front

What is a linear function?

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the dependent variable (y) with respect to the independent variable (x). It indicates how steep the line is.

Front

What is the difference between positive and negative correlation?

Back

Positive correlation means that as one variable increases, the other variable also increases. Negative correlation means that as one variable increases, the other variable decreases.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) that the function can accept.

Front

How do you determine the rate of change from a graph?

Back

The rate of change can be determined by calculating the slope of the line on the graph, which is the change in y divided by the change in x (rise/run).

Front

What does a scatterplot show?

Back

A scatterplot shows the relationship between two variables by displaying data points on a two-dimensional graph.

Front

What is the equation of a line in slope-intercept form?

Back

Front

What does it mean if a scatterplot has no correlation?

Back

If a scatterplot has no correlation, it means there is no discernible relationship between the two variables; changes in one variable do not predict changes in the other.
