What is the opposite of −8?

_{Recognize opposite signs of numbers as indicating locations on opposite sides of 0 on the number line. (MAFS.6.NS.3.6a)}

Which of the statements is true?

_{Recognize that the opposite of the opposite of a number is the number itself, e.g., –(–3) = 3, and that 0 is its own opposite. (MAFS.6.NS.3.6a)}

• The opposite of the opposite of 8 is -8.

• The opposite of the opposite of 8 is -1/8.

• The opposite of the opposite of 8 is 1/8.

• The opposite of the opposite of 8 is 8.

Which quadrant contains the reflection of (-4, 8) over the x-axis?

_{Recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes. (MAFS.6.NS.3.6b)}

• I

• II

• III

• IV

The coordinates of point S are (-5,2). In which quadrant does point S lie?

_{Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane. (MAFS.6.NS.3.6b)}

• Quadrant I

• Quadrant II

• Quadrant III

• Quadrant IV

Sally walks to school every day. This coordinate graph represents a map showing the location of the school and Sally's home.

Which ordered pair represents the location of Sally's school?

_{Find and position pairs of integers and other rational numbers on a coordinate plane. (MAFS.6.NS.3.6c)}

• (-8,6)

• (6,8)

• (6,-8)

• (8,6)

What is the value of the y-coordinate that is 5 units down of (5, −8)?

_{Find and position pairs of integers and other rational numbers on a coordinate plane. (MAFS.6.NS.3.6c)}

The table below shows the low temperature in a town each day for four days. Which of the following lists the temperature in order from least to greatest.

_{Distinguish comparisons of absolute value from statements about order. (MAFS.6.NS.3.7d)}

• 1, -3, 5, -8

• -8, -3, 5, 1

• -8, -3, 1, 5

James, Bob, and George are playing a game. At the end of the game, James had scored -10 points, Bob 5 points, and George -3 points. If the object of the game is to score the most points, which of these claims is true?

_{Distinguish comparisons of absolute value from statements about order. (MAFS.6.NS.3.7d)}

• James won the game because 10 is located to the right of 3 and 5 on a number line.

• Bob won the game because 5 is located to the right of -3 and -10 on a number line.

• George scored better than Bob because -3 is to the left of 5 on the number line.

• James scored better than George because -10 is to the left of -3 on the number line.
