Front

What is the definition of absolute value?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction. For example, the absolute value of -5 is 5.

Front

What does it mean for a number to be below zero?

Back

A number is below zero if it is less than zero, indicating a negative value. For example, -3 is below zero.

Front

How do you identify the coordinates of a point on a coordinate grid?

Back

A point on a coordinate grid is identified by an ordered pair (x, y), where 'x' is the horizontal position and 'y' is the vertical position.

Front

What is the distance formula for points on a coordinate grid?

Back

The distance between two points (x1, y1) and (x2, y2) is calculated using the formula: Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What are the four quadrants of a coordinate grid?

Back

The four quadrants are: Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), Quadrant IV (x > 0, y < 0).

Front

What is the significance of Quadrant IV in a coordinate grid?

Back

Quadrant IV contains points where the x-coordinate is positive and the y-coordinate is negative.

Front

How do you determine the absolute value of a fraction?

Back

The absolute value of a fraction is found by taking the absolute value of the numerator and the denominator separately. For example, the absolute value of -8/5 is 8/5.

Front

What is the meaning of '12 degrees below zero'?

Back

'12 degrees below zero' means a temperature of -12 degrees Celsius.

Front

How do you plot a point with negative coordinates on a coordinate grid?

Back

To plot a point with negative coordinates, move left (for negative x) and down (for negative y) from the origin.

Front

What is the relationship between coordinates and their position on a grid?

Back

The coordinates determine the exact location of a point on the grid based on its horizontal (x) and vertical (y) distances from the origin.
