Math Problem Statement

The point (-4, 3) is shown on the graph. Write the coordinates for the image of this point after a translation 2 units to the right and then a reflection over the x-axis.

Solution

The problem on the screen asks to find the coordinates of the point (4,3)(-4, 3) after two transformations:

  1. Translation 2 units to the right.
  2. Reflection over the x-axis.

Let's break it down:

  1. Translation 2 units to the right:

    • To move the point 2 units to the right, you add 2 to the x-coordinate.
    • So, (4+2,3)=(2,3)(-4 + 2, 3) = (-2, 3).
  2. Reflection over the x-axis:

    • A reflection over the x-axis changes the sign of the y-coordinate.
    • The reflected point would be (2,3)(-2, -3).

Thus, the coordinates of the image of the point after both transformations are (2,3)(-2, -3).

Would you like further details on any step or have questions? Here are 5 related questions to expand on this topic:

  1. What happens when you reflect a point over the y-axis instead of the x-axis?
  2. How do you perform a translation vertically instead of horizontally?
  3. How would you describe a reflection over the origin?
  4. What are the general rules for reflecting a point over any given line?
  5. 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.
