Slope: (slope-intercept form & equations)

Front

What is the slope of a line?

Back

The slope of a line measures its steepness and direction. It is calculated as the ratio of the rise (change in y) over the run (change in x).

What is the slope-intercept form of a linear equation?

Front

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

Front

What does a positive slope indicate about a line?

Back

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

Front

What does a negative slope indicate about a line?

Back

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

What does a slope of zero mean?

Back

A slope of zero means the line is horizontal, indicating that there is no change in y as x changes.

Front

What does an undefined slope mean?

Back

An undefined slope means the line is vertical, indicating that there is no change in x as y changes.
