Coordinate Planes

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Front

What are the axes in a coordinate plane?

Back

The x-axis (horizontal) and the y-axis (vertical) are the two lines that define the coordinate plane.

Front

What is an ordered pair?

Back

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

Front

What does the first number in an ordered pair represent?

Back

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

Front

What does the second number in an ordered pair represent?

Back

The second number represents the position along the y-axis.

Front

What are the coordinates of the origin?

Back

The coordinates of the origin are (0, 0).

Front

How do you plot a point on a coordinate plane?

Back

To plot a point, start at the origin, move along the x-axis to the first number, and then move vertically to the second number.

Front

What is the significance of the point (0, 0)?

Back

The point (0, 0) is called the origin and is the starting point for all coordinates on the plane.

Front

What is the coordinate of point A if it is located 3 units right and 2 units up from the origin?

Back

The coordinate of point A is (3, 2).

Front

What is the coordinate of point B if it is located 4 units left and 5 units down from the origin?

Back

The coordinate of point B is (-4, -5).
