COORDINATE GRID 6TH PERIOD

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 (x, y).

Front

What does the x-coordinate represent in a point (x, y)?

Back

The x-coordinate represents the horizontal position of a point on the coordinate grid, indicating how far to move left or right from the origin (0, 0).

Front

What does the y-coordinate represent in a point (x, y)?

Back

The y-coordinate represents the vertical position of a point on the coordinate grid, indicating how far to move up or down from the origin (0, 0).

Front

How do you reflect a point over the y-axis?

Back

To reflect a point (x, y) over the y-axis, change the sign of the x-coordinate, resulting in the point (-x, y).

Front

What is the distance formula between two points (x1, y1) and (x2, y2)?

Back

The distance formula is d = √((x2 - x1)² + (y2 - y1)²), which calculates the straight-line distance between two points on a coordinate plane.

Front

If a point is at (2, 3), what is its reflection over the x-axis?

Back

The reflection of the point (2, 3) over the x-axis is (2, -3).

Front

What is the distance between the points (5, 5) and (1, 5)?

Back

The distance is 4 units, calculated as |5 - 1| = 4.

Front

How do you find the distance between two points on a horizontal line?

Back

To find the distance between two points on a horizontal line, subtract the x-coordinates and take the absolute value of the result.

Front

What is the significance of the origin in a coordinate grid?

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect, serving as the reference point for all other points on the grid.

Front

How do you determine the number of units between two points on a coordinate grid?

Back

To determine the number of units between two points, calculate the absolute difference between their coordinates along the relevant axis.
