Chapter 5 Coordinate Plane

Front

What is the coordinate plane?

Back

A two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis), used to locate points using ordered pairs.

Front

What are the four quadrants of the coordinate plane?

Back

Quadrant I (positive x, positive y), Quadrant II (negative x, positive y), Quadrant III (negative x, negative y), Quadrant IV (positive x, negative y).

Front

What is an ordered pair?

Back

A pair of numbers (x, y) that represent a point on the coordinate plane, where 'x' is the horizontal position and 'y' is the vertical position.

Front

How do you find the distance between two points in different quadrants?

Back

You use addition to combine the absolute differences of their x-coordinates and y-coordinates.

Front

What does the x-coordinate represent in an ordered pair?

Back

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

Front

What does the y-coordinate represent in an ordered pair?

Back

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

Front

How do you reflect a point over the y-axis?

Back

Change the sign of the x-coordinate while keeping the y-coordinate the same.

Front

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

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect, serving as the reference point for all other points.

Front

What are the coordinates of the point located 3 units right and 2 units up from the origin?

Back

(3, 2).

Front

How do you write the coordinates of a point in Quadrant II?

Back

The x-coordinate is negative and the y-coordinate is positive.
