0.75
What is the absolute value of 174?
What is the origin on the coordinate plane?
The point (0,0), in the middle
What are two strategies to find the distance of two points on the coordinate plane?
- count on graph or make graph
- Add or subtract the absolute values of the coordinates
1,457
Which is greater, 3.65 or 3 1/2? How do you know?
3.65 is greater
3 1/2 is written as 3.5; 3.65 > 3.5.
3.65 is further to the right on the number line.
Insert an inequality symbol (<, >, or =) to make the statement true.
|-4.5| _____ |-3.5|
> "greater than"
Is the y-axis horizontal or vertical?
If the point (-2, 3) is reflected over the y-axis, what is the coordinate pairs of the new point?
Vertical
(2, 3)
You are finding the distance between two points that both have a (+, -) sign pattern. If the y values are the same, would you use the x or y values to find the distance between the points? Would you add or subtract the absolute values?
x values - subtract
Which is greater, -500 or -400?
Give a real world scenario that could be represented using the integer -400.
-400 is greater
-400 > -500
He withdrew $400 from the bank account.
Order the values -0.1, -0.75, 1.2, and 0.5 from least to greatest.
-0.75, -0.1, 0.5, 1.2
What are the symbols used to show absolute value?
Find |0|.
| x |
0
The coordinate pair (-4, 7) is reflected over the x-axis. What is the coordinate pair of the new point? (-4, -7)
(-4, -7)
Does the equation |y|+|y|=d show how to find the distance of two points in the same quadrant or in different quadrants?
Different quadrants
Mrs. Holland's score in a game is 99 points away from zero. If Troy's score is the opposite of Mrs. Holland’s and is a positive value, what is Mrs. Holland's score?
-99
Which is greater, -2/3 or -3/4?
-2/3 is greater
-2/3 is written as -0.66.. and -3/4 is written as -0.75, -0.66 > -0.75. -0.66 is further to the right on the number line.
True or false?
"Absolute value is always positive."
What is absolute value? Write a sentence to explain.
True
Absolute value is the distance of a number from zero.
What quadrant has negative x values and positive y values (-, +)?
Find the distance between (-1.5, -6.5) and (-2.5, -6.5).
1 unit
