Points and Quadrants
The coordinate plane is like a map divided into four sections called quadrants. These quadrants are created when the x-axis (horizontal) and y-axis (vertical) cross each other. Each position on this map has an address called coordinates in the form (x,y).
Each quadrant has its own pattern of positive and negative values. The first quadrant (top right) has both positive x and y values (x,y). The second quadrant (top left) has negative x but positive y −x,y. The third quadrant (bottom left) has both negative x and y −x,−y. And the fourth quadrant (bottom right) has positive x but negative y x,−y.
When plotting points, start at the origin (0,0) where the axes meet. The x-value tells you how far to move horizontally (right for positive, left for negative). The y-value tells you how far to move vertically (up for positive, down for negative). It's like following treasure map directions!
Fun Fact: Think of quadrants like neighborhoods in a city. The origin (0,0) is downtown where all the main streets cross, and each quadrant has its own special pattern of addresses!
