What is the slope of a line?

Back

The slope of a line is a measure of its steepness, usually represented as 'm'. It is calculated as the change in y (vertical) divided by the change in x (horizontal) between two points on the line.

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

What does it mean if the slope is positive?

Back

A positive slope indicates that as x increases, y also increases, meaning the line rises from left to right.

Front

What does it mean if the slope is negative?

Back

A negative slope indicates that as x increases, y decreases, meaning the line falls from left to right.

Front

What does a slope of zero indicate?

Back

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

Front

What does an undefined slope indicate?

Back

An undefined slope indicates a vertical line, where x remains constant and there is no change in x as y changes.

Front

Given the points (20,8) and (9,16), what is the slope?

Back

The slope is -8/11.

Front

Given the points (19,3) and (20,3), what is the slope?

Back

The slope is 0.

Front

Given the points (-4,7) and (-6,-4), what is the slope?

Back

The slope is 11/2.

Front

Given the points (17,-13) and (17,8), what is the slope?

Back

The slope is undefined.
