Slope & Slope Formula

Front

What is the slope formula?

Back

The slope formula is m = (y2 - y1) / (x2 - x1), where m is the slope, (x1, y1) and (x2, y2) are two points on a line.

Front

What does 'm' represent in the slope formula?

Back

'm' represents the slope of the line.

Front

Find the slope between the points (2, 7) and (5, 8).

Back

The slope is 1/3.

Front

Find the slope between the points (1, 4) and (5, 9).

Back

The slope is 5/4.

Front

Find the slope of a line that rises 3 units for every 4 units it runs.

Back

The slope is 3/4.

Front

Find the slope of a line that falls 2 units for every 5 units it runs.

Back

The slope is -2/5.

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 negative, what does that indicate about the line's direction?

Back

A negative slope indicates that the line descends from left to right.

Front

If the slope of a line is positive, what does that indicate about the line's direction?

Back

A positive slope indicates that the line ascends from left to right.
