Types of Slope

Front

What is a positive slope?

Back

A positive slope indicates that as the x-value increases, the y-value also increases. The line rises from left to right.

Front

What is a negative slope?

Back

A negative slope indicates that as the x-value increases, the y-value decreases. The line falls from left to right.

Front

What is a zero slope?

Back

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

Front

What is an undefined slope?

Back

An undefined slope occurs when a line is vertical. The x-value does not change, leading to a division by zero in the slope formula.

Front

How do you determine 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 vertical line have?

Back

A vertical line has an undefined slope.

Front

What type of slope does a horizontal line have?

Back

A horizontal line has a zero slope.

Front

If a line rises from left to right, what type of slope does it have?

Back

It has a positive slope.

Front

If a line falls from left to right, what type of slope does it have?

Back

It has a negative slope.

Front

What is the slope of a line that is perfectly vertical?

Back

The slope is undefined.
