First & Last Name Class Title Period Date Topic Questions, Subtitles, Headings, Etc. Class Notes 2 1/2” 3 to 4 sentence summary across the bottom of the last page of the day’s notes

Summary is added at the end of ALL note pages on the subject (not page) Summary added AFTER questions are finished Summary should answer the problem stated in the subject.

In the beginning of the year, I created a seating chart for my classes: - 5 rows of desks with 4 desks in each row. -Brian sits in the third row at the second desk (3,2) -D’wanda sits in the second row at the third desk (2,3). Are these seats the same? No!! The seats (3,2) and (2,3) are called ordered pairs because the order in which the pair of numbers is written is important!!

Who is sitting in desk (4,2)? ABCDE F A GHIJ K P LMNO QRST N

Number Lines: First you learned about the basic (counting) number line Objectives SWBAT: Draw the coordinate plan and label all important aspects Later on, you were introduced to zero and negatives… which completed the number line:

Number Lines: Breakthrough!!! Take a 2 nd number line, standing it on its end, and cross the 1 st number line at zero Objectives SWBAT: Draw the coordinate plan and label all important aspects

Axes Number lines drawn like this are called “axes” (pronounced “ACK-seez”) – more than ONE axis Objectives SWBAT: Draw the coordinate plan and label all important aspects The horizontal number line x- axis: y- axis: The vertical number line

Coordinate Plane Two number lines, or axes, one vertical & one horizontal, that intersect at their zero points, the origin. origin (0,0) Objectives SWBAT: Draw the coordinate plan and label all important aspects A pair of numbers that correspond to the point where the two axes (number lines) cross each other Origin

Objectives SWBAT: Draw the coordinate plan and label all important aspects y-coordinate: The first value in a coordinate pair. Indicates position on the x-axis The 2 nd value in a coordinate pair. Indicates position on the y-axis x-coordinate: Ordered Pair Used to locate points on a coordinate plane

Example: Graph (-3, 2) Objectives SWBAT: Draw the coordinate plan and label all important aspects In an ordered pair, the first number is the x-coordinate and the 2 nd number is the y- coordinate Ordered Pair y-coordinate: x-coordinate:

What is the ordered pair for A? 1.(3, 1) 2.(1, 3) 3.(-3, 1) 4.(3, -1) A

What is the ordered pair for B? B 1.(3, 2) 2.(-2, 3) 3.(-3, -2) 4.(3, -2)

What is the ordered pair for C? 1.(0, -4) 2.(-4, 0) 3.(0, 4) 4.(4, 0) C

What is the ordered pair for D? D 1.(-1, -6) 2.(-6, -1) 3.(-6, 1) 4.(6, -1)

Write the ordered pairs that name points A, B, C, and D. A = (1, 3) B = (3, -2) C = (0, -4) D = (-6, -1) A B C D

The x-axis and y-axis separate the coordinate plane into four regions, called quadrants. II (-, +) I (+, +) IV (+, -) III (-, -) Quadrants Objectives SWBAT: Draw the coordinate plan and label all important aspects Homework Read: Page. 60 Do: problems, p60, 1 - 4

Name the quadrant in which each point is located (-5, 4) 1.I 2.II 3.III 4.IV 5.None – x-axis 6.None – y-axis

Name the quadrant in which each point is located (-2, -7) 1.I 2.II 3.III 4.IV 5.None – x-axis 6.None – y-axis

Name the quadrant in which each point is located (0, 3) 1.I 2.II 3.III 4.IV 5.None – x-axis 6.None – y-axis

Review Problems Objectives SWBAT: Draw the coordinate plan and label all important aspects

Reflection Objectives SWBAT: Draw the coordinate plan and label all important aspects Thinking about previous lessons on solving equations, explain how you believe rwe can apply this to graphing.
