The coordinate plane is also called as Cartesian plane. It was invented by the French mathematician Rene Descartes in the 17 th century. The horizontal scale is called the x-axis.
Like a number line, the values increase and are positive as we move to the right from the zero. The values are negative and decrease as we move to the left from zero. The vertical scale is called the y-axis. The values on this axis are positive and increase as we go up from the zero. As we move down from zero, the values are negative and decreasing.
The set of x and y values are called ordered pair, also called as coordinate , represented as x, y. The first value shows the distance from x-axis and the second value shows the distance from the y-axis. Take a look at the similar writing assignments. The origin is the point of intersection of the x-axis and the y-axis. Hence, it does not lie in any of the quadrants. The first number in an ordered pair is the x-coordinate. The second number is the y-coordinate. The coordinate axes divide the plane into four regions called quadrants.
A coordinate plane is a two-dimensional plane formed by the intersection of a vertical line called y-axis and a horizontal line called x-axis. These are perpendicular lines that intersect each other at zero, and this point is called the origin. The quadrant is a very simple tool that allows the user to determine his or her latitude by measuring the altitude of a heavenly body. When used in celestial navigation or astronomy, altitude means the angle of elevation between the horizon and celestial bodies like the sun, planets, moon, or stars.
Quadrant I: The first quadrant is in the upper right-hand corner of the plane. Both x and y have positive values in this quadrant. Quadrant II: The second quadrant is in the upper left-hand corner of the plane. X has negative values in this quadrant and y has positive values. Any of the 4 areas made when we divide up a plane by an x and y axis, as shown. See: Quadrant circle. These two axes divide the paper into 4 parts.
Rachid Ridao Pundit. How many types of quadrants are there? All Four Quadrants. Learn all four quadrants of a coordinate system. The plane of the graph paper is divided into four regions by the coordinate axes and the four regions are called quadrants.
Yannick Heather Teacher. Is Quadrant 1 positive or negative? In Quadrant I, both the x— and y-coordinates are positive; in Quadrant II , the x-coordinate is negative, but the y-coordinate is positive; in Quadrant III both are negative; and in Quadrant IV, x is positive but y is negative.
Ousama Eliane Teacher. Is Quadrant 4 positive or negative? For an angle in the fourth quadrant the point P has positive x coordinate and negative y coordinate. The quadrants in which cosine, sine and tangent are positive are often remembered using a favorite mnemonic.
Yuanyuan Rafaj1 Teacher. How are quadrants labeled on a graph? Look at the label on the x-axis. Gertrudis Bauerschmitt Teacher. What is the origin of a graph? In mathematics, an origin is a starting point on a grid. It is the point 0,0 , where the x-axis and y-axis intercept. The origin is used to determine the coordinates for every other point on the graph.
Liboria Sklarski Reviewer. How do you graph? To graph a linear equation, we can use the slope and y-intercept. Locate the y-intercept on the graph and plot the point.
From this point, use the slope to find a second point and plot it. Draw the line that connects the two points. Grau Lluch Reviewer. What is a ordered pair in math? Coordinate system and ordered pairs. An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of x, y. The first number corresponds to the x-coordinate and the second to the y-coordinate.
