Slope Formula Practice

Front

What is the slope formula?

Back

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

Front

What does a positive slope indicate?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as x increases, y decreases.

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.

Front

If the rise is 3 and the run is 4, what is the slope?

Back

Slope = 3/4.

Front

If the rise is -2 and the run is 5, what is the slope?

Back

Slope = -2/5.

Front

What is the slope of the line represented by the points (1, 2) and (3, 6)?

Back

Slope = (6 - 2) / (3 - 1) = 4/2 = 2.

Front

What does a slope of zero mean in a real-world context?

Back

It means there is no change in the dependent variable as the independent variable changes.

Front

How do you determine the slope from a graph?

Back

Count the rise over the run between two points on the line.
