The sun is the energy source for the water cycle
Answer:
- <u><em>a reflection of the line segment across the y-axis </em></u>
Explanation:
The transformations of the end points are:
Preimage Image
The means that, for every end point, the x-coordinate changes the sign and the y-coordinate remains unchanged.
That rule is:
- (x, y) → (- x, y): this is<em> a reflection across the y-axis</em>.
Keeping the y-coordinate and changing the sign of the x-coordinate is a reflection across the y -axis. It is like a mirror image, where the mirror is placed along the y-axis. The figure keeps the same distance from the y-axis (the mirror) but changes sides, which is represented by the change of x to - x, while the altitude (the y-coordinate) keeps unchanged.
