12/3 LL: 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

How do you find the slope of a line given two points?

Back

To find the slope, use the formula: slope (m) = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

Front

What does a positive slope indicate?

Back

A positive slope indicates that as you move from left to right on the graph, the line rises.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as you move from left to right on the graph, the line falls.

Front

What is a zero slope?

Back

A zero slope means the line is horizontal, indicating no change in vertical distance as you move along the line.

Front

What is an undefined slope?

Back

An undefined slope occurs when a line is vertical, meaning there is no change in horizontal distance.

Front

If a line has a slope of -5/4, what type of slope is it?

Back

It is a negative slope.

Front

If a line has a slope of 2/1, what type of slope is it?

Back

It is a positive slope.

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.
