Answer:
Is a reflection across the x-axis
Step-by-step explanation:
The complete question is
Point D (9,-8) is reflected to D' (9,8). Is it on the x axis or y axis?
we know that
The rule of the reflection of a point across the x-axis is
(x,y)-----> (x,-y)
the x-coordinate remains the same, but the y-coordinate is transformed into its opposite
In this problem we have
D (9, -8) ------> D' (9, 8)
The y-coordinate is transformed into its opposite
therefore
Is a reflection across the x-axis
