Best Answer

Because the x axis is horizontal and the y axis is vertical and they both are perpendicular to each other at the point of origin (0, 0)

In an ordered pair like (2, 5), the first number is the x-coordinate. It is the horizontal distance to the right from the Origin to that point.

The x value is the first of a coordinate pair and tells you how far from the y axis the point is.

In the Cartesian coordinate system, a point represents a position in a two-dimensional space or plane. This means that that point has an x-value and a y-value. This is written as (x,y) and the entire paranthesis is the coordinate. Examples of coordinates: (3,6) and (-2, 12).

If ... the square of (the x-coordinate of the point minus the x-coordinate of the center of the circle) added to the square of (the y-coordinate of the point minus the y-coordinate of the center of the circle) is equal to the square of the circle's radius, then the point is on the circle.

you should know exactly what it is 2nd Answer: You nothing about its x coordinate, but the y coordinate = 0

If two numbers are given, the first one is usually the x-coordinate, the second, the y-coordinate.

No. In an ordered pair for a point in the xy-plane the first number is the x-coordinate and the second is the y-coordinate. (2, 5) is the point with an x-coordinate of 2 and a y-coordinate of 5; (5, 2) is the point with an x-coordinate of 5 and a y-coordinate of 2. Only if the x- and y- coordinates are equal are the points the same point. However, the point (5, 2) is the reflection of the point (2, 5) in the line y = x.

It is called that point...(say, 5, -4) but in the x coordinate. a question may be...Find the x cooriinate of 5, -4, and the x coordinate of it would just be caalled the x coordinate of 5, -4

The quadrant where a point has a negative x coordinate and a negative y coordinate is located in quadrant 3.

When a point lies on the y-axis, its x coordinate must be zero.
