Types of slope

Front

What is a positive slope?

Back

A positive slope means that as you move from left to right on a graph, the line rises. It indicates a direct relationship between the two variables.

Front

What is a negative slope?

Back

A negative slope means that as you move from left to right on a graph, the line falls. It indicates an inverse relationship between the two variables.

Front

What does a zero slope indicate?

Back

A zero slope indicates that the line is horizontal, meaning there is no change in the y-value as the x-value changes.

Front

What does an undefined slope indicate?

Back

An undefined slope occurs when a line is vertical, meaning the x-value does not change while the y-value changes.

Front

How do you calculate the slope of a line?

Back

The 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 goes up to the right have?

Back

A line that goes up to the right has a positive slope.

Front

What type of slope does a line that goes down to the right have?

Back

A line that goes down to the right has a negative slope.

Front

What type of slope does a horizontal line have?

Back

A horizontal line has a zero slope.

Front

What type of slope does a vertical line have?

Back

A vertical line has an undefined slope.

Front

If a line has a slope of 2, what does that mean?

Back

A slope of 2 means that for every 1 unit you move to the right, the line rises 2 units.
