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 four quadrants of a coordinate plane?

Back

The four quadrants are the regions created by the x-axis and y-axis: Quadrant I (positive x, positive y), Quadrant II (negative x, positive y), Quadrant III (negative x, negative y), Quadrant IV (positive x, negative y).

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

How do you identify the x-coordinate in an ordered pair?

Back

The x-coordinate is the first number in an ordered pair, indicating the horizontal position on the coordinate plane.

Front

How do you identify the y-coordinate in an ordered pair?

Back

The y-coordinate is the second number in an ordered pair, indicating the vertical position on the coordinate plane.

Front

What does it mean to plot a point on a coordinate plane?

Back

To plot a point means to mark its location on the coordinate plane using its ordered pair (x, y).

Front

What is the difference between the x-axis and y-axis?

Back

The x-axis is the horizontal line on the coordinate plane, while the y-axis is the vertical line.

Front

What is an ordered pair?

Back

An ordered pair is a set of two numbers (x, y) that represent a specific point on a coordinate plane.

Front

How do you plot the ordered pair (3, 5)?

Back

Start at the origin (0,0), move 3 units to the right (x-coordinate), and then move 5 units up (y-coordinate).

Front

What is the significance of the first quadrant?

Back

In the first quadrant, both x and y coordinates are positive.
