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). It is used to locate points using ordered pairs.

Front

What are ordered pairs?

Back

Ordered pairs are pairs of numbers used to locate points on a coordinate plane, written in the form (x, y). The first number represents the x-coordinate, and the second number represents the y-coordinate.

Front

What does the x-coordinate represent?

Back

The x-coordinate represents the horizontal position of a point on the coordinate plane.

Front

What does the y-coordinate represent?

Back

The y-coordinate represents the vertical position of a point on the coordinate plane.

Front

How do you identify a point on the coordinate plane?

Back

To identify a point, you use its ordered pair (x, y), where you move x units along the x-axis and y units along the y-axis.

Front

What is the origin in a coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented by the ordered pair (0, 0).

Front

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

Back

The first number in an ordered pair indicates the position along the x-axis.

Front

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

Back

The second number in an ordered pair indicates the position along the y-axis.

Front

How do you plot the point (3, 4) on a coordinate plane?

Back

To plot (3, 4), move 3 units to the right on the x-axis and 4 units up on the y-axis.

Front

What is the coordinate of the point located 2 units left and 3 units up from the origin?

Back

The coordinate is (-2, 3).
