Question



  1.  the ordered pair that each point represents;
  2. the quadrant in which the ordered pair is plotted (placed);
  3. the x= line and the y = line that help to form the ordered pair.

Your answers should look like this:

   Point E
   ordered pair (4, 2)
   plotted in Quadrant I
   formed by the line x = 4 and the line y = 2

Each problem will count for 3 points.

Here are the points for which the information above should be listed:

1. M
2. O
3. L
4. N
5. P

The graph that you will use is shown below.

As was shown in the Practice Walk, the image is a graph of the x-y coordinate plane. The x-y coordinate plane shows 5 points and the student is supposed to list the ordered pair, the quadrant in which the ordered pair is plotted/located and the x = lines and y = lines that help to form each of the ordered pairs.  

Answer
This is basically self-explainitory

Quadrant I (x,y)
Quadrant II (-x,y)
Quadrant III (-x,-y)
Quadrant IV (x,-y)

You notice how in "formed by the line x = 4 and the line y = 2", now look at "ordered pair (4, 2)" you notice how in (x,y), x = 4 and y = 2, this is basically where the vertical line meets with the horiztonal line.

For ex:

1.)
Point M

ordered pair (x,y), since i don't have a picture of where the points are i can't tell you what (x,y) is

plotted in Quadrant ---, using what i told you each Quadrant is made up of, you can feel in the blank.

formed by the line x = x1 and the line y = y2
For this one, i can't answer x1 and y2, since i don't have a picture of the graph.

But maybe with my explaination, you can do it on your on.
