Slope of a line

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in vertical distance (rise) divided by the change in horizontal distance (run).

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 means that the line is horizontal, indicating no change in y-value as x-value changes.

Front

What is an undefined slope?

Back

An undefined slope occurs when a line is vertical, meaning there is no change in x-value as y-value changes.

Front

How do you calculate the slope between two points?

Back

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

Front

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

Back

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

Front

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

Back

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

Front

If a line is horizontal, what is its slope?

Back

The slope of a horizontal line is zero.

Front

If a line is vertical, what is its slope?

Back

The slope of a vertical line is undefined.
