Unit 3 Standard Math Test Review

Front

What is the value that represents a position below sea level?

Back

Negative value (e.g., -60 feet represents 60 feet below sea level).

Front

How do you calculate the distance between a point above sea level and a point below sea level?

Back

Add the absolute values of both positions (e.g., 25 feet above and 10 feet below: |25| + |10| = 35 feet apart).

Front

What does the absolute value of a number represent?

Back

The distance of that number from zero on the number line, regardless of direction (e.g., |−5| = 5).

Front

In which quadrant of the Cartesian plane is the point (2, -3) located?

Back

Quadrant IV (where x is positive and y is negative).

Front

What is the lowest temperature among the following: -12°F, -20°F, -5°F, -8°F, -15°F?

Back

-20°F (the most negative value represents the lowest temperature).

Front

What is the definition of a coordinate plane?

Back

A two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Front

What are the coordinates of a point in Quadrant I?

Back

Both x and y coordinates are positive (e.g., (3, 4)).

Front

How do you identify the y-coordinate of a point?

Back

The second number in the ordered pair (x, y) represents the y-coordinate.

Front

What is the significance of negative numbers in real-world contexts?

Back

They can represent values below a reference point, such as sea level or temperatures below zero.

Front

What is the formula to find the distance between two points on a number line?

Back

Distance = |x1 - x2|, where x1 and x2 are the positions of the two points.
