Slope & Slope Formula

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 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

Find the slope given the points (2,3) and (4,7).

Back

Slope = (7 - 3) / (4 - 2) = 4/2 = 2.

Front

Find the slope given the points (0,0) and (3,9).

Back

Slope = (9 - 0) / (3 - 0) = 9/3 = 3.

Front

Find the slope given the points (-1,2) and (2,5).

Back

Slope = (5 - 2) / (2 - (-1)) = 3/3 = 1.

Front

What is the rate of change in the context of slope?

Back

The rate of change refers to how much y changes for a change in x.

Front

If the slope is -1/3, what does this mean in terms of direction?

Back

It means that for every 3 units you move to the right, you move down 1 unit.
