Coordinate plane review

Learning Objectives Identify and label the x-axis, y-axis, origin, and four quadrants of the coordinate plane. Accurately plot ordered pairs (x, y) in all four quadrants and on the axes. Read and write the coordinates of a given point on the coordinate plane. Determine the quadrant in which a point lies based on the signs of its coordinates. Understand the meaning of positive and negative coordinates in relation to the origin. Recognize real-world situations where the coordinate plane is used. Ever wonder how a pilot knows exactly where to fly, or how a video game character moves across the screen? 🎮 It's all thanks to a system called the coordinate plane! In this lesson, we'll review the fundamental concepts of the coordinate plane, including its key components,...

TermDefinitionExample Coordinate PlaneA two-dimensional surface formed by the intersection of two perpendicular number lines, used to locate points.Imagine a grid on a map where you can pinpoint any specific address. x-axisThe horizontal number line on the coordinate plane.When you move left or right from the center, you are moving along the x-axis. y-axisThe vertical number line on the coordinate plane.When you move up or down from the center, you are moving along the y-axis. OriginThe point where the x-axis and y-axis intersect, represented by the ordered pair (0, 0).The exact center of the coordinate plane, like the starting point of a treasure hunt. Ordered PairA pair of numbers (x, y) that specifies the location of a point on the coordinate plane, where 'x' is the horizonta...

Ordered Pair Notation $(x, y)$ Always write the x-coordinate first, followed by the y-coordinate, enclosed in parentheses. The x-coordinate tells you how far to move horizontally (left/right), and the y-coordinate tells you how far to move vertically (up/down). Origin Coordinates $(0, 0)$ The origin is the starting point for plotting all other points. It has an x-coordinate of 0 and a y-coordinate of 0. Quadrant Signs Quadrant I: $(+, +)$ Quadrant II: $(−, +)$ Quadrant III: $(−, −)$ Quadrant IV: $(+, −)$ The signs of the x and y coordinates determine which quadrant a point lies in. Points on the axes (where x=0 or y=0) are not considered to be in any quadrant.
