## What are the points on a Cartesian plane?

The position of a point on a Cartesian plane is represented by referring to it in terms of a horizontal line and a vertical line, which are called the x-axis and y-axis respectively. The point of intersection of the x-axis and the y-axis is called the origin. Often, we draw a set of axes on graph paper as shown below.

**What is plane in Cartesian coordinate system?**

A Euclidean plane with a chosen Cartesian coordinate system is called a Cartesian plane. The two axes divide the plane into four right angles, called quadrants. The quadrants may be named or numbered in various ways, but the quadrant where all coordinates are positive is usually called the first quadrant.

### How is the Cartesian plane set up?

A Cartesian plane (named after French mathematician Rene Descartes, who formalized its use in mathematics) is defined by two perpendicular number lines: the x-axis, which is horizontal, and the y-axis, which is vertical. Using these axes, we can describe any point in the plane using an ordered pair of numbers.

**Which of the following points in the Cartesian plane is on the YY axis?**

the origin

The horizontal axis in the coordinate plane is called the x-axis. The vertical axis is called the y-axis. The point at which the two axes intersect is called the origin. The origin is at 0 on the x-axis and 0 on the y-axis….

x-coordinate | y-coordinate |
---|---|

2 | 4 |

3 | 6 |

4 | 8 |

## How do you find the points on a coordinate plane?

Locating a point in the coordinate plane Count in either the positive (right) or negative (left) direction along the x-axis to determine a point’s horizontal position. Count in either the positive (up) or negative (down) direction along the y-axis to determine a point’s vertical position, as shown in the figure below.

**Which of the following points is in the first quadrant of the Cartesian plane?**

Answer :- Here, point ( 4, 3 ) has x > 0 and y > 0 so it is in first quadrant.

### How are positions measured in the Cartesian plane?

All positions are measured relative to a “central” point called the origin, whose coordinates are ( 0, 0). For example, the point ( 5, 2) is 5 units to the right of the origin and 2 units up, as shown in the figure. Negative coordinate numbers tell us to go left or down. See the other points in the figure for examples.

**Which is the first number in the Cartesian plane?**

Cartesian Plane and Ordered Pairs. The x-coordinate is always the first number in the pair and the y-coordinate is always the second number in the pair. The point illustrated on the Cartesian plane to the left shows the following ordered pair: (4, -2) wherein the point is represented by a black dot. Therefore (x,y) = (4, -2).

## How are ordered pairs formed in the Cartesian plane?

Cartesian planes are formed by two perpendicular number lines intersect. Points on the cartesian plane are called “ordered pairs,” which become extremely important when illustrating the solution to equations with more than one data point. Simply put, though, the Cartesian plane is really just two number lines…

**How to choose points in the coordinate plane?**

When choosing your points try to include both positive and negative values as well as zero. Begin by choosing a couple of values for x e.g. -2, -1, 0, 1 and 2 and calculate the corresponding y values.
