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 are ordered pairs?

Back

Ordered pairs are pairs of numbers used to represent the position of a point on a coordinate grid, written in the form (x, y).

Front

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

Back

To calculate the distance between two points (x1, y1) and (x2, y2), use the formula: Distance = |x2 - x1| + |y2 - y1|.

Front

What is the distance between the points (5, 6) and (5, 8)?

Back

2 units.

Front

What is the distance between the points (-7, 8) and (2, 8)?

Back

9 units.

Front

What happens to the coordinates of a point when it is reflected over the y-axis?

Back

The x-coordinate changes sign, while the y-coordinate remains the same.

Front

Reflect the point (2, -4) over the y-axis. What is the new point?

Back

(-2, -4).

Front

What is the length of the longest side of a rectangle with coordinates (3, 2), (-2, 2), (-2, -1), (3, -1)?

Back

5 units.

Front

What is the formula for the length of a side of a rectangle on a coordinate grid?

Back

Length = |x2 - x1| or |y2 - y1| depending on the orientation.

Front

What does reflecting over the y-axis change?

Back

It changes the x-coordinate.
