rate of change and slope

Front

What is the definition of slope?

Back

The slope of a line is a measure of its steepness, calculated as the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line.

What does a positive slope indicate?

Back

A positive slope indicates that as the x-value increases, the y-value also increases.

What is the significance of a slope of zero?

Back

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

What is the significance of an undefined slope?

Back

An undefined slope occurs in a vertical line, where x remains constant while y changes.

How do you interpret the slope in a real-world context?

Back

In a real-world context, the slope represents the rate of change between two quantities, such as speed or cost per item.
