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 represent the position of a point on a coordinate plane, written in the form (x, y). The first number is the x-coordinate, and the second number is the y-coordinate.

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a coordinate plane where the y-coordinate is zero. It runs left to right.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a coordinate plane where the x-coordinate is zero. It runs up and down.

Front

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

Back

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

Front

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

Back

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

Front

What is the significance of positive and negative coordinates?

Back

Positive coordinates indicate positions to the right (for x) or above (for y) the origin, while negative coordinates indicate positions to the left (for x) or below (for y) the origin.

Front

What is the first quadrant in a coordinate plane?

Back

The first quadrant is the area where both x and y coordinates are positive. It is located in the upper right section of the coordinate plane.

Front

What is the second quadrant in a coordinate plane?

Back

The second quadrant is the area where x coordinates are negative and y coordinates are positive. It is located in the upper left section of the coordinate plane.
