Finding Slope

Front

What is the formula to find the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

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

Back

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

If the slope of a line is 2, what does this mean in terms of rise over run?

Back

For every 2 units of rise, there is 1 unit of run.

Front

Find the slope of the points (4, 10) and (4, 2).

Back

Undefined

Front

If a line has a slope of 0, what can be said about its direction?

Back

The line is horizontal.

Front

If a line has a slope of -2, what does this mean in terms of rise over run?

Back

For every 2 units of fall, there is 1 unit of run.
