According to economists, this episode of great recession was resulted from a sudden busting of house bubble in US, where the house bubble was caused by rapid growth of improper regulation on sub-prime mortgages (Merriam 2009; Wang 2009; Whitney 2007).
When working with equations that have two variables, the coordinate plane is an important tool. It's a way to draw pictures of equations that makes them easier to understand. To create a coordinate plane, start with a sheet of graph or grid paper. Next, draw a horizontal line.
= 2. The coordinate of C and the radius are used in the standard equation of the circle to obtain the equation: (x - 1) + (y - 2) = 2. (x - 1) + (y - 2) = 4. Go here and set h, k and r parameters into applet and plot the circle.Verify graphically that the equation is that of a circle with the diameter as given above. 2.
