Slope flashcard P458

Front

What is slope?

Back

Slope is a measure of the steepness or incline of a line, typically represented as a fraction.

Front

How is slope calculated?

Back

Slope is calculated by dividing the rise (vertical change) by the run (horizontal change).

Front

What does a positive slope indicate?

Back

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

Front

What does a negative slope indicate?

Back

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

Front

What does a zero slope indicate?

Back

A zero slope indicates a horizontal line where there is no vertical change.

Front

What does an undefined slope indicate?

Back

An undefined slope indicates a vertical line where there is no horizontal change.

Front

What is the slope of a line that rises 3 units for every 1 unit it runs?

Back

The slope is 3/1.

Front

What is the slope of a line that falls 1 unit for every 3 units it runs?

Back

The slope is -1/3.

Front

What is the formula for slope?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.
