Coordinate Grid

Front

What is a coordinate grid?

Back

A coordinate grid is a two-dimensional plane 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 is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate grid, written in the form (x, y).

Front

In the ordered pair (7, 8), which number is the x-coordinate?

Back

7

4

Front

What is the origin in a coordinate grid?

Back

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

Front

How do you write an ordered pair?

Back

An ordered pair is written in the form (X, Y).

Front

What are the four quadrants in a 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 does the x-axis represent?

Back

The x-axis represents the horizontal line in a coordinate grid where the y-coordinate is zero.

Front

What does the y-axis represent?

Back

The y-axis represents the vertical line in a coordinate grid where the x-coordinate is zero.

Front

What is the significance of the coordinates (0, y)?

Back

The coordinates (0, y) lie on the y-axis, where the x-coordinate is zero.
