Math Problem Statement
Which algebraic rule represents the transformation shown on the grid?
Solution
To determine the algebraic rule for the transformation shown, we observe the given points and their transformations:
- Points , , and reflect across the x-axis to become , , and .
- The original and transformed points have coordinates as follows:
- is at approximately and reflects to at .
- is at approximately and reflects to at .
- is at approximately and reflects to at .
This shows that each point's y-coordinate has been negated, while the x-coordinate remains the same. This is a reflection over the x-axis.
Algebraic Rule
The rule representing this transformation is:

Tip: When reflecting across the x-axis, only the y-coordinate changes sign, while the x-coordinate remains constant.
