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). It is used to locate points using ordered pairs (x, y).

Front

What does the ordered pair (0, 0) represent?

Back

The ordered pair (0, 0) represents the origin point on a coordinate grid, where the x-axis and y-axis intersect.

Front

What are the four quadrants of a coordinate grid?

Back

The four quadrants are: Quadrant I (x positive, y positive), Quadrant II (x negative, y positive), Quadrant III (x negative, y negative), Quadrant IV (x positive, y negative).

Front

How do you plot the point (3, 2) on a coordinate grid?

Back

To plot (3, 2), start at the origin (0, 0), move 3 units to the right (positive x-direction), and then move 2 units up (positive y-direction).

Front

What is the x-coordinate in the ordered pair (4, -1)?

Back

The x-coordinate is 4.

Front

What is the y-coordinate in the ordered pair (-2, 5)?

Back

The y-coordinate is 5.

Front

In which quadrant is the point (-3, -4) located?

Back

The point (-3, -4) is located in Quadrant III.

Front

What does it mean if a point has a negative x-coordinate?

Back

A negative x-coordinate means the point is located to the left of the origin on the x-axis.

Front

What does it mean if a point has a negative y-coordinate?

Back

A negative y-coordinate means the point is located below the origin on the y-axis.

Front

How do you find the distance between two points on a coordinate grid?

Back

To find the distance between two points, use the distance formula: d = √((x2 - x1)² + (y2 - y1)²).
