CFU Identify the x-coordinate in the ordered pair below. Identify the y-coordinate in the ordered pair below. (6, -9) “The x-coordinate is ______________.” “The y-coordinate is ______________.” (6, 2) and (2, 6) do not describe the same point on the coordinate plane. Explain why not. In your own words, what is an ordered pair? “An ordered pair is ______________.” Points on the Coordinate Plane (4, 5) xy (5, -4) (4, 5) (-4, -5) (-4, 5) 1 crossing (synonym) 2 crossing at a 90 degree angle 3 shows (synonym) Vocabulary

  7. Relevance • An ordered pair describes the location of a point on the coordinate plane using x- and y-coordinates. • The x-coordinate is the position of the point along the x-axis. • The y-coordinate is the position of the point along the y-axis. Plotting ordered pairs will help you understand information in real life. 1 Information in real life is often presented in graphs on a coordinate plane. Most maps use a grid system that works like a coordinate plane. 2 Plotting ordered pairs will help you tell where things are located. Plotting ordered pairs will help you do well on tests. 3 CFU Does anyone else have another reason why it is relevant to plot ordered pairs? (Pair-Share) Why is it relevant to plot ordered pairs? You may give one of my reasons or one of your own. Which reason is more relevant to you? Why? Sample Test Question: 20. Which of the following describes the point M on the graph? The point is at (6, -4). The distance of the point from the y-axis is 6. The point is at (-6, 4). The distance of the point along the y-axis is -6. Yes No Yes No Yes No Yes No M
