Coordinate Plane Basics

X and Y Axes

• The x-axis is the horizontal line on a grid that shows values from left to right.
• The y-axis is the vertical line on a grid that shows values from bottom to top.
• The x-axis and y-axis intersect at a point called the origin (0, 0).

Grid Paper

• Grid paper is a special type of paper with a grid of lines that help us create a coordinate plane.
• The grid is made up of squares or rectangles that are the same size.
• Grid paper can be used to draw shapes, create patterns, and plot points.

Coordinate Planes

• A coordinate plane is a grid with x and y axes that helps us locate points.
• The coordinate plane is divided into four quadrants: top-right, top-left, bottom-right, and bottom-left.
• Each quadrant has its own set of coordinates (x, y) that tell us the location of a point.

Plotting Points

• To plot a point, we need to know its coordinates (x, y).
• The x-coordinate tells us how many units to move to the right or left from the origin.
• The y-coordinate tells us how many units to move up or down from the origin.
• Example: To plot the point (3, 4), we move 3 units to the right and 4 units up from the origin.

Key Concepts:

• The x-axis shows horizontal values.
• The y-axis shows vertical values.
• The origin is the point where the x and y axes intersect.
• Grid paper helps us create a coordinate plane.
• A coordinate plane has four quadrants.
• Coordinates (x, y) tell us the location of a point.
• We need to know the coordinates to plot a point.

Axes and Coordinates

• The x-axis is a horizontal line on a grid that displays values from left to right.
• The y-axis is a vertical line on a grid that displays values from bottom to top.
• The x-axis and y-axis intersect at the origin, which is the point (0, 0).

Grid Paper

• Grid paper is a special type of paper with a grid of lines that helps create a coordinate plane.
• The grid is composed of identical squares or rectangles.

Coordinate Plane

• A coordinate plane is a grid with x and y axes that helps locate points.
• The coordinate plane is divided into four quadrants: top-right, top-left, bottom-right, and bottom-left.
• Each quadrant has its own set of coordinates (x, y) that define a point's location.

Plotting Points

• To plot a point, you need to know its coordinates (x, y).
• The x-coordinate indicates how many units to move to the right or left from the origin.
• The y-coordinate indicates how many units to move up or down from the origin.
• Example: To plot the point (3, 4), move 3 units to the right and 4 units up from the origin.
