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.

If a linear function has a slope of -5/3, what does this indicate about the function?

Back

A slope of -5/3 indicates that for every 3 units increase in x, the value of y decreases by 5 units, showing a negative correlation.

What is the significance of a slope of 0 in a linear function?

Back

A slope of 0 indicates a horizontal line, meaning there is no change in y as x changes.
