Describe how you would plot this point: (2, -5)
What is you begin at the origin (0,0), go left 2 units and then down 5 units to plot your point?
An integer that represents "56 meters below sea level"
What is "-56"?
What is the opposite of -24?
24
Label the four quadrants on your coordinate plane whiteboard
Roman numerals counter-clockwise
I, II, III, IV
What point on the coordinate plane represents sea level?
What is the origin (0,0)?
An integer to represent "a deposit of fifty dollars."
What is "+50"?
What is the opposite of 78
-78
(-9.5, 2) is in which Quadrant?
II
The distance between (0, -18) and (0, 5).
23 units
Out of this list, name the number that is NOT an integer: 25, 0, -25, 0.25
What is 0.25? Since the other numbers are whole numbers they would represent integers. 0.25 is a decimal is it is more of a rational number.
What is the opposite of 0?
0
Name an ordered pair in Quadrant IV.
Answers vary: must have (x, -y)
(13, -5), (2, -8), etc.
If the point (-2, 5) is reflected over the x-axis, what is the new ordered pair?
(-2, -5)
The absolute value of "-125" is...
What is 125? Absolute value is the distance from zero; so that means "-125" is 125 PLACES from zero.
Name an integer that is GREATER THAN the opposite of -3
ex. 4, 5, 70, 1000
What Quadrant is (6, 0) in?
It is not in a quadrant, it is on the x-axis.
The distance between (7, 5) and (13, 5)?
What is the distance of 6.
Lake Erie is 210 feet below sea level. Name the integer that represent the elevation of Lake Erie. Then state its absolute value.
(You MUST be able to tell me which is the integer and which is the absolute value)
Integer: -210
|-210|=210
Name a rational number that is LESS THAN the opposite of 5.
Any number that is less than -5
ex: -5.1, -7, -1000, -90.5
If you reflect a point in Quadrant I over the y-axis, what Quadrant are you in?
