Coordinate Grid

Front

What is the 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

How do you plot a point on the coordinate grid?

Back

To plot a point, start at the origin (0,0), move along the x-axis to the x-coordinate, and then move vertically to the y-coordinate.

Front

What does the point (3, -4) represent on the coordinate grid?

Back

The point (3, -4) represents a location that is 3 units to the right of the origin and 4 units down.

Front

What are the coordinates of the origin on the coordinate grid?

Back

The coordinates of the origin are (0, 0).

Front

What is the x-axis?

Back

The x-axis is the horizontal line on the coordinate grid where the y-coordinate is zero.

Front

What is the y-axis?

Back

The y-axis is the vertical line on the coordinate grid where the x-coordinate is zero.

Front

How do you identify the quadrant of a point?

Back

The quadrant of a point is determined by the signs of its coordinates: Quadrant I (positive, positive), Quadrant II (negative, positive), Quadrant III (negative, negative), Quadrant IV (positive, negative).

Front

What does it mean if a point lies on the x-axis?

Back

If a point lies on the x-axis, its y-coordinate is zero.

Front

What does it mean if a point lies on the y-axis?

Back

If a point lies on the y-axis, its x-coordinate is zero.

Front

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

Back

The distance between two points can be calculated using the distance formula: d = √((x2 - x1)² + (y2 - y1)²).
