What are the two parts of the Dimension Assumption?
Any plane has points on it that are NOT on any given line on it.
Any space has points within it that are NOT on any given plane in it.

On the Line PQ, Point Q is at coordinate (- 4) and Point P is at coordinate (12).
What is PQ?
For the points, you will need to show the math for calculating PQ on the board.
PQ = 16
Distance Formula: PQ = |12 - (- 4)|

E is between A and C.
IF AC = 24 in. and CE = 13 in. What is AE = ?
AE = 11 in.
500
On a line, point A lies on coordinate 12, point C lies on coordinate 13, and point B lies on coordinate 11.
Give a proper name for the line AND give the assumption that says it is possible to assign each point a coordinate.
"Line CAB", "Line BAC", "Line AC", "Line AB", "Line BA", "Line CA", or "Line AC" (Not "Line ABC" or "ACB")
Number Line Assumption:
Every line is a set of points that can be put into a one-to-one correspondence with the real numbers, with any point on it corresponding to 0 and any other point corresponding to 1.
500
To earn the points, you must show the work for solving the problem on the board.

7x + 8 = 36
7x = 28
x = 4
