Slope & Slope Formula

Front

What is the slope formula?

Back

The slope formula is m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on a line.

Front

Find the slope given the points (2, −7) and (−1, 6).

Front

What type of slope does a horizontal line have?

Back

Zero slope

Front

What type of slope does a vertical line have?

Back

Undefined slope

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises as it moves from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls as it moves from left to right.

Front

If the slope of a line is zero, what does that mean?

Back

It means the line is horizontal and does not rise or fall.

Front

If the slope is undefined, what does that mean?

Back

It means the line is vertical and does not have a defined slope.
