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

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What does a positive slope indicate about a line?

Back

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

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

Front

What does an undefined slope indicate?

Back

An undefined slope indicates that the line is vertical.

Front

Calculate the slope of the line passing through (1, 2) and (3, 6).

Back

m = (6 - 2) / (3 - 1) = 4 / 2 = 2.

Front

Calculate the slope of the line passing through (2, 3) and (5, 7).

Back

m = (7 - 3) / (5 - 2) = 4 / 3.

Front

If a line passes through the points (4, 5) and (4, 1), what is the slope?

Back

The slope is undefined because the x-coordinates are the same.

Front

What is the slope of a line that is perfectly horizontal?

Back

The slope is 0.

Front

What is the slope of a line that is perfectly vertical?

Back

The slope is undefined.
