2.

FLASHCARD QUESTION

Front

How can you identify the y-intercept from a graph?

Back

The y-intercept can be identified by locating the point where the line intersects the y-axis.

3.

FLASHCARD QUESTION

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x, indicating how steep the line is.

4.

FLASHCARD QUESTION

Front

How is slope calculated between two points (x1, y1) and (x2, y2)?

Back

Slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

5.

FLASHCARD QUESTION

Front

What is a positive slope?

Back

A positive slope indicates that as x increases, y also increases, resulting in an upward slant from left to right.

6.

FLASHCARD QUESTION

Front

What is a negative slope?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward slant from left to right.

7.

FLASHCARD QUESTION

Front

What does a slope of zero indicate?

Back

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