Coordinate Grids

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

In the ordered pair (X,Y), which number represents the X coordinate?

Back

X represents the horizontal position on the coordinate grid.

Front

In the ordered pair (X,Y), which number represents the Y coordinate?

Back

Y represents the vertical position on the coordinate grid.

Front

How do you write the ordered pair for the point located 3 units right and 2 units up from the origin?

Back

(3,2)

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

If you move 5 units left and 3 units down from the origin, what is the ordered pair?

Back

(-5,-3)

Front

What does the point (0,0) represent on a coordinate grid?

Back

The point (0,0) is called the origin, where the x-axis and y-axis intersect.

Front

What is the significance of the first number in an ordered pair?

Back

The first number indicates the position along the x-axis.
