Coordinate Plane

Front

What is the coordinate plane?

Back

A two-dimensional surface formed by the intersection of a vertical line (Y-axis) and a horizontal line (X-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

What is the origin in the coordinate plane?

Back

The point (0, 0) where the X-axis and Y-axis intersect.

Front

How do you identify the quadrant of an ordered pair?

Back

By checking the signs of the x and y coordinates: positive x and positive y is Quadrant I, negative x and positive y is Quadrant II, negative x and negative y is Quadrant III, positive x and negative y is Quadrant IV.

Front

What is the X-axis?

Back

The horizontal line on the coordinate plane where the y-coordinate is zero.

Front

What is the Y-axis?

Back

The vertical line on the coordinate plane where the x-coordinate is zero.

Front

What is the distance between two points on the same vertical line?

Back

The absolute difference between their y-coordinates.

Front

What is the distance between two points on the same horizontal line?

Back

The absolute difference between their x-coordinates.

Front

What is absolute value?

Back

The distance of a number from zero on the number line, always a non-negative value.
