Unit 1 Lesson 1.1.1-2
Points & Lines

Distance b/n points. Has length, but no width or height.

​Line Segment

Singularity, coordinate (x, y).

​Point

Concepts:

​Procedure:

1) Plot points using (x, y) as directions starting at the origin.
2) To find the (x, y) values work backwards from the point to the origin.
3)To solve for missing lengths, setup numerical or algebraic operations to solve for the unknown.

Plot the point, and give the quadrant:
(-3, 1)
(5, 2)
(-2, 0)

​

​Example 1:

State the coordinates of each point:

​

​Example 2:

Solve for x, and find the length of the line if:
AB = 3x+1
BC= 5x-2
AC = 9x-7
