Slope of a line

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in vertical distance divided by the change in horizontal distance.

Front

What does a positive slope indicate?

Back

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

Front

What does a zero slope indicate?

Back

A zero slope indicates a horizontal line, meaning there is no change in vertical distance as you move horizontally.

Front

What does an undefined slope indicate?

Back

An undefined slope indicates a vertical line, meaning there is no change in horizontal distance.

Front

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

Back

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

Front

If a line rises from left to right, what is the slope?

Back

The slope is positive.

Front

If a line falls from left to right, what is the slope?

Back

The slope is negative.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is zero.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.
