8th Grade NC Check-in C Review

Front

What does a positive association between two variables indicate?

Back

As one variable increases, the other variable also increases.

Front

What do the x and y-axes represent in a scatter plot?

Back

The x-axis typically represents the independent variable, while the y-axis represents the dependent variable.

Front

What is the rate of change in a linear function?

Back

The rate of change is the slope of the line, indicating how much the y-value changes for a unit change in the x-value.

Front

What does a good representation of data in a line graph mean?

Back

It means the line accurately reflects the trend and pattern of the data points.

Front

What is a positive non-linear correlation?

Back

A relationship where as one variable increases, the other variable also increases, but not at a constant rate.

Front

What is a scatter plot?

Back

A graph that displays values for typically two variables for a set of data.

Front

What is the definition of a linear function?

Back

A function that graphs to a straight line, represented by the equation y = mx + b.

Front

What is the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the equation y = mx + b.

Front

How do you determine the slope of a line from a graph?

Back

The slope is determined by the rise over run, or the change in y divided by the change in x between two points on the line.

Front

What does it mean if a scatter plot shows no correlation?

Back

It means there is no discernible pattern or relationship between the two variables.
