An ordered pair describes the location of a point on the coordinate plane. The coordinate plane is made up of a horizontal number line and a vertical number line that cross each other at zero. The horizontal number line is called the x-axis and the vertical number line is called the y-axis. The numbers on the x-axis are positive to the right of zero and negative to the left of zero. The numbers on the y-axis are positive above zero and negative below zero. The point where the x- and y-axis intersect is called the origin. Each point on the coordinate plane consists of an x-coordinate and a y-coordinate. The x-coordinate always appears first in the ordered pair, (x, y). The ordered pair which describes the location of the origin is (0, 0). To plot an ordered pair on the coordinate plane, first start at the origin. If the x-coordinate is positive, you travel that many units to the right. If the x-coordinate is negative, you travel that many units to the left. From this new location on the x-axis, if the y-coordinate is positive, you travel up that many units and if it is negative you travel down that many units. Take a look at a couple of examples. PLOT: (4, 2) |dw:1350112444507:dw| I went over 4 on my x-axis, and up 2 on the y-axis.

How about a tutorial on finding error bounds from Hermite Interpolation

4. Compassionate

Isn't that rather advanced for OpenStudy students? Only 2 or 3 people will even understand it.

5. Hero

But, but...OS is for students of all ages and levels.

Ha ha, I guess you're right. I'll consider it. Putting together a tutorial on that won't be easy, but I'll do my best. Don't expect to see it within' a week. It'll most likely be up around Halloween.

7. lgbasallote

people still do these huh

8. Compassionate

Huh? I've never seen someone post one of these questions.

9. lgbasallote

i meant the tutorials

10. Compassionate

Well, I just do them to help the community.

You said, "No one does these." It was vague wording. I took it as you were.

I appreciate it... @Compassionate

I have just mentioned the axes.. Which is positive or which one is negative..
