The x-coordinate of a point is also calledĢ. A point whose x coordinate and y coordinate is zero is known asĥ. If a point is in 4 th quadrant, then the point will be in the form The Cartesian coordinate system, also known as the coordinate plane, is used to graph lines, circles, parabolas, points, and other mathematical objects. The power of the coordinate plane lies in the use of ordered pairs. See below figure and answer the following questionsĮxplanation: The x -coordinate of point B (2, -3) is =2ġ0. In 2 nd quadrant y is positive and x isġ1. Ordinate of all the points on the x-axis isĮxplanation: Coordinates of any point on x-axis is (x, 0). So, x can take any value but the ordinate will always be 0.ġ2. The point which lies on the y-axis at a distance of 2.5 units in the positive direction of the y-axis isĮxplanation: Coordinates of any point on y-axis is (0, y). In the question it is given that the point lies on y-axis in the positive direction. Hence, the value of y should be positive.ġ3. If y-coordinate of a point is zero then the point lies onġ6.īoth abscissa and ordinate of a point are positive inĮxplanation: Coordinates of any point in 1st quadrant is (x, y).įor example: (2,3) lies in 1st quadrant and here both abscissa and ordinate are positiveĮxplanation: Abscissa of a point is negative in II and III quadrants i.e., (-x, y) and (-x, -y)ġ5. (d) Does not lie in the same quadrant Answerġ7. (b) B, D and E lies in different quadrantsĮxplanation: From the below graph we can clearly observe that A and C lies in I quadrantĪnd B, D and E lies in different quadrantsġ8. The mirror of a point (1,2) with respect to x axis isĮxplanation: To find the reflection of point (1,2) on x-axis, keep x-coordinate constant and see the reflection of the point along x-axis. What are xcoordinate and ycoordinate called. We will look at the x-axis and the y-axis, and the plane formed by these two.

Are you giving all the chapters of Maths Class 9 MCQs with Answers which are given in CBSE syllabus for 2021-22 ? The idea which has given rise to an important branch of Mathematics known as Coordinate Geometry. Cartesian coordinate system: A system which describe the position of a point in a plane is called Cartesian system. Cartesian coordinate axis: Let us draw a horizontal line XX’ and a vertical line YY’ in a plane. Yes, we are providing all the chapters of Maths Class 9 MCQs with Answers.This is a fun little problem. Here I setup the coordinate you specified as a string in a table, using a WITH Statement.

This avoided having to create a table with the column in order to demonstrate how to get it out again. In your example, the string has the coordinates delimited by a space. Using the function SPLIT_PART, I separated the string into each of it's numbers. Then I cast them to the type the ST_MAKEPOINT expects (float). The point you specified is at 10 degrees by -23 degrees. Which is in the south western hemisphere in the middle of the ocean.
