New centroid $(\frac{17}{3}, 1)$ $(17/3, 1)$

Explanation:

The old centroid is at $(\frac{17}{3}, - 1)$ $(17/3, -1)$ . If we are going to reflect the triangle across the x-axis, only the y value will change sign. From -1 to 1.

$(\frac{17}{3}, 1)$ $(17/3, 1)$ is the new centroid.

God bless....I hope the explanation is useful.
