See the number line which represents he elevation of three towns in feet. Bob plots town D at 0. He plots town E at -25. What does 0 and -25 represent in this situation?
0 represents sea level/Town D is at sea level.
-25 represents Town E- it is 25 feet below sea level.

Point A is at (-6,9) on a coordinate plane. It is reflect over the X axis, and then reflected over the Y axis.
What is the ordered pair of the final point?
How do you determine this answer?
It goes to (-6,-9) first (over the x axis, x stays the same and y is the opposite.)
THEN goes to (6, -9) to finish. (over the y axis, y stays the same and x is opposite.)

Using the number line. Town E is at -40. Town F is 200 feet higher than town E. What is the elevation of town F?
240 feet.
I-40I + I200I = 240

Write the elevation for each artifact using a positive integer, 0, or negative integer. How do you determine if it should be positive, negative, or a 0?
Artifact 1: dinosaur bones- found 1500 feet below sea level.
Artifact 2: Hunter's tool- found 562 feet above seat level.
Artifact 3: Necklace- found at sea level
Artifact 4: Cooking bowl- found 26 feet below sea level.
Dino bones: -1500
Tool- 562
Necklace- 0
Bowl- -26
Use a 0 for sea level. Above is positive, below is negative.

Use your coordinate plane in the whiteboard sleeve.
Plot point B at (3,6) and point A at (-1, -3).
There are two vertices of a rectangle. The rectangle should have a width of 4 units and a length of 9 units.
Plot the other two points of the vertices and label them C and D.
Point C or D: (3, -3)
Point C or D: (-1,6)
