Is the slope positive, negative, zero, or undefined

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. This 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. This 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 mean?

Back

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

Front

How can you identify a positive slope on a graph?

Back

You can identify a positive slope by observing that the line moves upward from left to right.

Front

How can you identify a negative slope on a graph?

Back

You can identify a negative slope by observing that the line moves downward from left to right.

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.

Front

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

Back

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

Front

If a line has a slope of -3, what does this mean?

Back

A slope of -3 means that for every 1 unit you move to the right, the line falls 3 units.
