If you mean at the Origin (where both X and Y cross), then the coordinates would be (0,0)================================-- If the 'x' coordinate is zero, then the point is on t he y-axis.-- If the 'y' coordinate is zero, then the point is on the x-axis.-- If both coordinates are zero, then the point must be the onethat's on both axes ... the 'origin'.
The first and second coordinate. X is the first coordinate and y is the second.
the x coordinate is always before the y coordinate just like in the alphabet
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.
A line is just a line, but the y-coordinate (the point where the line intersects the y-axis) is termed the y intercept. This point has an x coordinate that is always zero and the y coordinate can be positive, zero, or negative
