It is represented in the form of (x, y) whereas x and y have given values
Reflecting a point P, in the x axis is finding another point Q such that they both have the same x-coordinate and that the y-coordinate of Q is the additive inverse of the y-coordinate of P. Thus, is P is 4.5 above the x-axis, then Q is 4.5 below it and if P is below, then Q is above by the same distance.Reflection in the y-axis is similar except that now it is the y-coordinate that remains the same and the x-coordinate that changes. If P was to the left then Q is to the right (and conversely).
It is impossible to figure it out with just one coordinate and no line. Maybe your line extends through the x and y system and you were given one coordinate. Take that coordinate and find the rise over run (slope). Follow that rise over run all the way to the y-axis. Whatever point you are on once you hit the y-axis that is the y-intercept.
A point's y coordinate is its vertical position, or how high or low it is.
The y coordinate is 0.
The y coordinate is given below:
Compare it's position to the origin. The x coordinate is the number of units to the right of the origin. (If it is to the left of the origin the x coordinate is negative.) The y coordinate is the number of units above the origin. (If it is below, the y coordinate is negative.) The point is denoted (x,y) with the x coordinate in place of the x and the y coordinate in place of the y.
If two numbers are given, the first one is usually the x-coordinate, the second, the y-coordinate.

We will be able to identify the answer if we have the equation. We can only check on the coordinates from the given vertex.
The y-values (the second number) in each coordinate (point) given to you. For example, the point (4,8) would have a y-value of 8

A point's y coordinate is its vertical position, or how high or low it is.
The y-intercept of that line is the point (0, 21).
If a point lies on the x-axis, then you know that the y-coordinate is zero.
