![]() In the third quadrant, both the coordinates are negative. In the second quadrant, x-coordinate is negative whereas the y-coordinate is positive ![]() In the first quadrant, both the coordinates are positive. ![]() There are four corners you need to know about on the graph. A quadrant is ¼th part of a cartesian plane divided by coordinate axes. These two axes divide the cartesian plane into 4 parts each part is called a quadrant. Take a plain sheet of paper, draw one horizontal line called X-axis and one vertical line called Y-axis such that it intersects at a point O. The values that come first in ordered pairs are plotted along the horizontal line(x-axis) while the second number of ordered pairs is plotted along the vertical line(y-axis). Points on the cartesian plane are called ordered pairs written as (x, y). The Great Mathematician Rene Descartes' Latin name was Renatius Cartesius,who originally came up with the concept of a Cartesian plane named after him. For the Y-axis, numbers below zero are negative and numbers above are positive.Let us study What is cartesian plane in detail.The Cartesian Plane is also referred to as the X-Y plane or the coordinate plane.Ī graph with two perpendicular number lines used to describe any point in the plane using an ordered pair of numbers is called a Cartesian Plane or the coordinate plane where one is vertically referred to as a Y axis and the other is horizontally referred to as the X axis and both form right angles with one another. Numbers to the right of the zero on the X-axis are positive and the numbers to the left of zero are negative. The origin (O) is in the exact center of the graph intersecting point of the two axes. These two axes are perpendicular to each other. doi: 10.1111/j.1432-1033.1995.766_a.x.A Cartesian plane is a graph with two axes, one is called the x-axis and the other one is the y-axis.

Woolf pointed out that linear graphs are obtained when v is known exactly. 119–120, I described some graphical methods, stating that they were due to my friend Dr. Kurt Stern published a German translation of my book Enzymes, with numerous additions to the English text. However, Haldane indicated latter that Woolf had indeed found the three linear forms: Attribution to Woolf is often omitted, because although Haldane and Stern credited Woolf with the underlying equation, it was just one of the three linear transformations of the Michaelis–Menten equation that they initially introduced. It has been known by various different names, including Eadie plot, Hofstee plot and Augustinsson plot. In biochemistry, an Eadie–Hofstee plot (or Eadie–Hofstee diagram) is a graphical representation of the Michaelis–Menten equation in enzyme kinetics.
