1. The document discusses coordinate planes and identifying points using ordered pairs. It provides examples of ordered pairs and asks the reader to identify other coordinates.
2. It then discusses a vertical line l that passes through the point (3,7) and asks the reader to find 6 points on the line and 6 points not on the line, as well as how to tell if a point is on the line based on its coordinates.
3. Finally, it introduces transformations on coordinate planes and asks the reader questions about finding points with specific x- and y-coordinates or where the y-coordinate is less than the x-coordinate. It provides homework problems for further practice.
3. Other Coordinate l
Plane Practice:
(3, 7)
Line l is vertical and
passes through (3, 7).
a. Find 6 points on l.
b. Find 6 points not
on l.
c. How can you tell
if a point is or isn't
on l by looking at
its coordinates?

4. For you to think 1. The y‐axis is the only vertical line that passes
about: through (0, 0). What do the coordinates of the points
on the y‐axis have in common?
Do the points on the x‐axis follow the same pattern?
2. Graph a horizontal line through (‐2, 1) in a
coordinate plane. Name two other points on the line.

5. What about this? 3. Shade the region or set of points on a coordinate
plane where you find (a,b) in the following cases:
a. 3≤a≤4 and 0≤b≤1
b. 2≤a≤5 and 0≤b≤1
a. b.
