Slope (Rise Over Run)

Front

What is slope?

Back

Slope is a measure of the steepness of a line, calculated as the ratio of the vertical change (rise) to the horizontal change (run).

Front

What does a positive slope indicate?

Back

A positive slope indicates that as you move from left to right on a graph, the line rises.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as you move from left to right on a graph, the line falls.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

How do you calculate slope using two points?

Back

Slope (m) = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

Front

If a line rises 3 units and runs 2 units, what is the slope?

Back

The slope is 3/2.

Front

If a line falls 4 units and runs 1 unit, what is the slope?

Back

The slope is -4.

Front

What does a slope of 1 mean?

Back

A slope of 1 means that for every 1 unit you move up, you move 1 unit to the right.

Front

What does a slope of -1 mean?

Back

A slope of -1 means that for every 1 unit you move down, you move 1 unit to the right.
