FLASHCARD QUESTION

Front

What is the slope formula?

Back

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

FLASHCARD QUESTION

Front

What does a positive slope indicate about a line?

Back

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

3.

FLASHCARD QUESTION

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-values increase, the y-values decrease, meaning the line falls from left to right.

4.

FLASHCARD QUESTION

Front

What is the significance of a slope of zero?

Back

A slope of zero indicates a horizontal line, meaning there is no change in y as x changes.

5.

FLASHCARD QUESTION

Front

What does an undefined slope indicate?

Back

An undefined slope indicates a vertical line, where x remains constant while y changes.

6.

FLASHCARD QUESTION

Front

How do you determine the slope between two points?

Back

To determine the slope between two points, use the formula (y2 - y1) / (x2 - x1) and substitute the coordinates of the points.

FLASHCARD QUESTION

Front

What is the error in using addition instead of subtraction in the slope formula?

Back

Using addition instead of subtraction can lead to an incorrect calculation of the slope, resulting in a misrepresentation of the line's steepness.
