Objective The student will be able to: 1) identify each quadrant as I, II, III or IV 2) graph ordered pairs on a coordinate plane 3) identify which quadrant an ordered pair fall in.

Ordered pairs are used to locate points in a coordinate plane. y-axis (vertical axis) 5 -5 5 x-axis (horizontal axis) -5 origin (0,0)

In an ordered pair, the first number is the x-coordinate In an ordered pair, the first number is the x-coordinate. The second number is the y-coordinate. Graph. (-3, 2) 5 • -5 5 -5

What is the ordered pair for A? 5 (3, 1) (1, 3) (-3, 1) (3, -1) • A -5 5 -5

What is the ordered pair for B? (3, 2) (-2, 3) (-3, -2) (3, -2) 5 -5 5 • B -5

What is the ordered pair for C? (0, -4) (-4, 0) (0, 4) (4, 0) 5 -5 5 • C -5

What is the ordered pair for D? (-1, -6) (-6, -1) (-6, 1) (6, -1) 5 -5 5 • D -5

Write the ordered pairs that name points A, B, C, and D. 5 A = (1, 3) B = (3, -2) C = (0, -4) D = (-6, -1) • A -5 5 • D • B • C -5 Answers to the 4 previous slides

The x-axis and y-axis separate the coordinate plane into four regions, called quadrants. II (-, +) I (+, +) III (-, -) IV (+, -)

Name the quadrant in which each point is located (-5, 4) II III IV None – x-axis None – y-axis

Name the quadrant in which each point is located (-2, -7) II III IV None – x-axis None – y-axis

Name the quadrant in which each point is located (0, 3) II III IV None – x-axis None – y-axis

Answers (-5, 4) is in quadrant II (-2, -7) is in quadrant III (0, 3) is in quadrant 1
