Topic 7

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.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate grid, written in the form (x, y).

Front

How do you identify a point on a coordinate grid?

Back

You identify a point by its coordinates, which are given as an ordered pair (x, y), where 'x' is the horizontal position and 'y' is the vertical position.

Front

What does it mean to move east on a coordinate grid?

Back

Moving east means increasing the x-coordinate while keeping the y-coordinate the same.

Front

What does it mean to move north on a coordinate grid?

Back

Moving north means increasing the y-coordinate while keeping the x-coordinate the same.

Front

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

Back

You can find the distance by calculating the difference in their x-coordinates and y-coordinates, and using the Pythagorean theorem if needed.

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.

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 write the coordinates of point C located at (9, 2)?

Back

The coordinates of point C are written as (9, 2), where 9 is the x-coordinate and 2 is the y-coordinate.
