Slope Review

Front

What is the formula to calculate the slope of a line?

Back

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

Front

What does a positive slope indicate about a line?

Back

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

Front

What does a negative slope indicate about a line?

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 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

How do you find the rise in the slope formula?

Back

The rise is calculated as (y2 - y1).

Front

How do you find the run in the slope formula?

Back

The run is calculated as (x2 - x1).

Front

If a line passes through the points (2, 3) and (5, 11), what is the slope?

Back

Slope = (11 - 3) / (5 - 2) = 8/3.

Front

What type of slope does the graph of the equation y = 2x + 1 have?

Back

Positive slope.

Front

If the slope of a line is -4, what does this tell you about the line's direction?

Back

The line decreases as it moves from left to right.
