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 type of slope is represented by a horizontal line?

Back

Zero slope.

Front

What type of slope is represented by a vertical line?

Back

Undefined slope.

Front

What type of slope is represented by a line that goes down from left to right?

Back

Negative slope.

Front

What type of slope is represented by a line that goes up from left to right?

Back

Positive slope.

Front

If a line has a slope of 0, what does that mean?

Back

It means the line is horizontal and there is no vertical change as you move along the line.

Front

If a line has an undefined slope, what does that mean?

Back

It means the line is vertical and there is no horizontal change as you move along the line.

Front

Calculate the slope between the points (2, 3) and (4, 7).

Back

The slope is m = (7 - 3) / (4 - 2) = 4 / 2 = 2.

Front

What does a positive slope indicate about the relationship between x and y?

Back

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

Front

What does a negative slope indicate about the relationship between x and y?

Back

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