Math Problem Statement
Solution
The problem on the screen asks to find the coordinates of the point after two transformations:
- Translation 2 units to the right.
- Reflection over the x-axis.
Let's break it down:
-
Translation 2 units to the right:
- To move the point 2 units to the right, you add 2 to the x-coordinate.
- So, .
-
Reflection over the x-axis:
- A reflection over the x-axis changes the sign of the y-coordinate.
- The reflected point would be .
Thus, the coordinates of the image of the point after both transformations are .
Would you like further details on any step or have questions? Here are 5 related questions to expand on this topic:
- What happens when you reflect a point over the y-axis instead of the x-axis?
- How do you perform a translation vertically instead of horizontally?
- How would you describe a reflection over the origin?
- What are the general rules for reflecting a point over any given line?
- How do combined transformations like rotation and reflection affect a point's position?
Tip: When performing multiple transformations, always follow the order specified. For example, apply the translation first, then the reflection.
