Coordinate Grid

Front

What is the origin on a coordinate grid?

Back

The origin is the point (0,0) where the x-axis and y-axis intersect. It is the starting point for graphing points.

Front

In the ordered pair (4,9), what does the number 4 represent?

Back

The number 4 represents the x-coordinate.

Front

In the ordered pair (4,9), what does the number 9 represent?

Back

The number 9 represents the y-coordinate.

Front

How do you write an ordered pair?

Back

An ordered pair is written as (X,Y), where X is the x-coordinate and Y is the y-coordinate.

Front

Which axis runs horizontally on a coordinate grid?

Back

The x-axis runs horizontally.

Front

Which axis runs vertically on a coordinate grid?

Back

The y-axis runs vertically.

Front

What is the purpose of the x-axis?

Back

The x-axis is used to represent the horizontal values in a coordinate grid.

Front

What is the purpose of the y-axis?

Back

The y-axis is used to represent the vertical values in a coordinate grid.

Front

What does the point (3,2) indicate on a coordinate grid?

Back

The point (3,2) indicates that you move 3 units right on the x-axis and 2 units up on the y-axis.

Front

What is the distance from the origin to the point (4,5)?

Back

The distance can be calculated using the Pythagorean theorem: √(4^2 + 5^2) = √41.
