If a transformation moves points only up or down, how do the coordinates of the point change? What can you conclude about the co
ordinate notation for the transformation? The
?
does not change. The
?
has a positive constant added to it (for a translation up) or a negative constant added to it (translation down). The coordinate notation has the form (x, y) arrowright , where b is a real number, b
If a transformation moves points up or down, the X coordinate will not change, however, the Y coordinate will receive a positive constant if the points are moved up and it will receive a negative constant if the points are moved down.
This is because:
The X coordinate is more stable and remains constant with changes of points in the vertical direction.
The Y coordinate is less stable in this type of change and therefore it will be able to modify the nature of its variables, as the change takes place.
Thus, the notation of coordinates is directly dependent on the positioning of X and Y, and the Y coordinate becomes more influential, due to the diversity of its variables.
It is important to note that coordinate notation refers to the use of two numbers to find a point in two-dimensional space, quickly and safely.
