Question

1. a triangle has vertices at (3,3), (6,3), and (4.5,6). after reflecting the triangle over the x - axis, what are the new coordinates of the vertex (6,3)? a. (6, - 3) b. (-3,6) c. (-6, - 3) d. (-6,3)

Explanation:

Step1: Recall reflection rule

When reflecting a point $(x,y)$ over the x - axis, the rule is $(x,y)\to(x, - y)$.

Step2: Apply rule to given point

For the point $(6,3)$, using the rule $(x,y)\to(x, - y)$, we get $(6,3)\to(6,-3)$.

Answer:

a. $(6, - 3)$
