Finding the Slope of Lines

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, typically represented as 'm'. It is calculated as the ratio of the rise (change in y) to the run (change in x).

Front

What is the formula for calculating slope?

Back

Front

Find the slope of the line passing through the points (1, 8) and (3, 12).

Back

The slope is 2.

Front

What does a positive slope indicate about a line?

Back

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

Front

What does a negative slope indicate about a line?

Back

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

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

If a line has a slope of -5/3, what does this mean?

Back

This means for every 3 units the line moves to the right (run), it moves down 5 units (rise).

Front

How do you find the slope from a graph?

Front

What is the relationship between slope and parallel lines?

Back

Parallel lines have the same slope.
