Types of Slope

Front

What is slope?

Back

Slope is a measure of the steepness or incline of a line, typically represented as a ratio of the vertical change to the horizontal change between two points on the line.

Front

What are the four types of slope?

Back

The four types of slope are positive slope, negative slope, zero slope, and undefined slope.

Front

What does a positive slope indicate?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, resulting in an upward trend.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, resulting in a downward trend.

Front

What is zero slope?

Back

Zero slope occurs when a line is horizontal, meaning there is no vertical change as the x-value changes.

Front

What is undefined slope?

Back

Undefined slope occurs when a line is vertical, meaning there is no horizontal change as the x-value changes.

Front

How do you calculate slope?

Back

Slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

Front

What type of slope does a line that rises from left to right have?

Back

A line that rises from left to right has a positive slope.

Front

What type of slope does a line that falls from left to right have?

Back

A line that falls from left to right has a negative slope.

Front

If a line is horizontal, what is its slope?

Back

If a line is horizontal, its slope is zero.
