Front

What is a coordinate pair?

Back

A coordinate pair is a set of two numbers that define a point's position on a grid, written in the form (x, y).

Front

What does the x-coordinate represent in a coordinate pair?

Back

The x-coordinate represents the horizontal position of a point on the coordinate plane.

Front

What does the y-coordinate represent in a coordinate pair?

Back

The y-coordinate represents the vertical position of a point on the coordinate plane.

Front

How do you identify the opposite of a number on a number line?

Back

The opposite of a number is found by locating the point that is the same distance from zero but in the opposite direction.

Front

What is the ordered pair for point F if it is located at (3 1/2, 0)?

Back

The ordered pair for point F is (3.5, 0).

Front

What is the significance of the origin in a coordinate plane?

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect.

Front

How do you plot a point on a coordinate plane?

Back

To plot a point, start at the origin, move along the x-axis to the x-coordinate, and then move vertically to the y-coordinate.

Front

What is the definition of a number line?

Back

A number line is a straight line with numbers placed at equal intervals, used to represent real numbers.

Front

What is the value of the opposite of -18?

Back

The opposite of -18 is 18.

Front

How do you find the coordinates of a point on a grid?

Back

To find the coordinates, identify the horizontal (x) and vertical (y) positions of the point.
