what are the coordinates of the image of vertex d after a reflection across the x - axis? (5, 3) (-5, -3) (-3, 5) (3, -5)
Answer
Explanation:
Step1: Recall reflection rule
When reflecting a point $(x,y)$ across the $x - axis$, the rule is $(x,y)\to(x, - y)$.
Step2: Identify original coordinates
Assume the original coordinates of vertex D are $(3,5)$ (from the visible part of the graph where D seems to be located).
Step3: Apply reflection rule
Using the rule $(x,y)\to(x, - y)$ for the point $(3,5)$, we get $(3,-5)$.
Answer:
D. $(3, - 5)$
