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).

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).

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 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.
