C OORDINATE GEOMETRY COORDINATE GEOMETRY 155 7 7.1 Introduction In Class IX‚ you have studied that to locate the position of a point on a plane‚ we require a pair of coordinate axes. The distance of a point from the y-axis is called its x-coordinate‚ or abscissa. The distance of a point from the x-axis is called its y-coordinate‚ or ordinate. The coordinates of a point on the x-axis are of the form (x‚ 0)‚ and of a point on the y-axis are of the form (0‚ y). Here is a play for you. Draw a set

Coordinate geometry The Basics: Find the distance between two points using Pythagoras’ theorem. The midpoint is the average (mean) of the coordinates. The gradient = Parallel lines have the same gradient. The gradients of perpendicular lines have a product of -1. Straight Lines: Equation of a straight line is y = mx + c‚ where m = gradient‚ c = y-intercept. The equation of a line‚ if we know one point and the gradient is found using: (y - y1) = m(x - x1) (If given two points‚ find the

Arzumanov: Conceptual Geometry Syllabus Class Website: http://new.schoolnotes.com/sarzu Welcome to Conceptual Geometry! This course will use the textbook Geometry: Concepts and Applications. Conceptual Geometry builds upon the concepts presented in Algebra 1. New content is introduced as an extension of material previously mastered in the abovementioned course. A primary goal of Conceptual Geometry is the use of mathematical ideas in solving problems ranging from everyday applications to the real world and sciences

Wii Sports Versus Real Life Sports Real life sports and Wii Sports the video game have many similarities and differences to be considered when letting children choose which one they want to play. When children are not able to play real life sports because of weather or illnesses‚ Wii Sports can be a good‚ temporary alternative.

The way the monkey people talk about or to the jungle people‚ how the jungle people talk about them‚ and how they treat others can make the reader feel like they are symbolizing bullies in real life. The way the monkey people attack is also how the monkey people are symbolizing real bullies. The Jungle-people

friends and real life friends. Many people think that these two both have the same level of friendship. Unlike those people‚ I think that having real friends that you personally see and talk with is priceless and irreplaceable.

First I looked at how the monsters relate to life today and I found out that Calypso a sea nymph is a person holding us back from our goals within life. She is misleading and selfish. She cares only about herself. The Cyclops‚ because he has only one eye‚ relates to how people who see through only one perspective. Circe represents wealth and power.
