Slope & Slope Formula

Front

What is the slope formula?

Back

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

Front

How do you find the slope between two points (3,2) and (4,7)?

Back

Using the slope formula: m = (7 - 2) / (4 - 3) = 5.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases, meaning the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, meaning the line falls from left to right.

Front

What is the slope of the line that passes through the points (-4, -1) and (-2, -5)?

Back

Using the slope formula: m = (-5 - (-1)) / (-2 - (-4)) = -2.

Front

What is the slope of the line that passes through the points (-2,-9) and (-1,-3)?

Back

Using the slope formula: m = (-3 - (-9)) / (-1 - (-2)) = 6.

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 a line has a slope of 0, what type of slope is it?

Back

It is a zero slope, indicating a horizontal line.

Front

If a line has a slope of 1, what type of slope is it?

Back

It is a positive slope, indicating the line rises as it moves from left to right.
