The coordinates of a point on a coordinate grid are (−3, 7). The point is reflected across the x-axis to obtain a new point. The coordinates of the reflected point are
A. (−3, −7)
B. (3, −7)
C. (−3, 7)
D. (3, 7)
I think the answer is A
I would have preferred if you had said,
"I know the answer is A"
the answer is A people
What is the answer
To reflect a point across the x-axis, we need to negate the y-coordinate while keeping the x-coordinate unchanged.
Given that the original point is (-3, 7), we will negate the y-coordinate, which is 7, to get our reflected point.
Negating 7 gives us -7, so the coordinates of the reflected point are (-3, -7), represented by option A.
Therefore, your answer is correct. The coordinates of the reflected point are (-3, -7) (option A).
