A triangle has points A(2, 2), B(2, 4), and C(6, 3) and is reflected over the x-axis. A'B'C' are the coordinates of the reflected image. What is the B' coordinate?
the reflection takes (x,y) -> (x,-y)
so, just change the sign of B's y-coordinate.
To find the reflected image of a point over the x-axis, we need to keep the x-coordinate the same and change the sign of the y-coordinate.
Given that the original coordinate is B(2, 4), the x-coordinate remains the same, which is 2. To reflect it over the x-axis, we change the sign of the y-coordinate, making it negative. Thus, the y-coordinate of B' will be -4.
Therefore, the coordinates of the reflected point B' are (2, -4).
