Points on Coordinate Grid McFarland 25

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). Each point on the grid is identified by an ordered pair of numbers (x, y).

Front

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

Back

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

Front

What is the x-axis?

Back

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

Front

What is the y-axis?

Back

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

Front

How do you identify a point on a coordinate grid?

Back

A point on a coordinate grid is identified by an ordered pair (x, y), where 'x' is the horizontal distance from the origin and 'y' is the vertical distance from the origin.

Front

What is the distance between two points on a coordinate grid?

Back

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

Front

What is the significance of the first number in an ordered pair?

Back

The first number in an ordered pair represents the x-coordinate, indicating the horizontal position of the point.

Front

What is the significance of the second number in an ordered pair?

Back

The second number in an ordered pair represents the y-coordinate, indicating the vertical position of the point.

Front

How do you plot a point on a 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 is Point A if it is located at (4,7)?

Back

Point A is located 4 units to the right of the origin and 7 units up.
