Slope of a Line: +, -, 0, No

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, usually represented as 'm'. It indicates how much the y-coordinate changes for a unit change in the x-coordinate.

Front

What does a positive slope indicate?

Back

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

Front

What does a negative slope indicate?

Back

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

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-coordinate as the x-coordinate changes.

Front

What does an undefined slope indicate?

Back

An undefined slope indicates that the line is vertical, meaning the x-coordinate does not change while the y-coordinate changes.

Front

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

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

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

Back

The slope is positive.

Front

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

Back

The slope is negative.
