Slope of a line

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, usually represented as a fraction (rise/run).

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does a positive slope indicate?

Back

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

Front

What does a negative slope indicate?

Back

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

Front

What does a zero slope indicate?

Back

A zero slope indicates a horizontal line, meaning there is no rise.

Front

What does an undefined slope indicate?

Back

An undefined slope indicates a vertical line, where the run is zero.

Front

If the slope is 5/2, what does this mean?

Back

This means for every 2 units you move horizontally, the line rises 5 units.

Front

If the slope is -4/3, what does this mean?

Back

This means for every 3 units you move horizontally, the line falls 4 units.

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.
