Answer:
Option B
Step-by-step explanation:
The slope of the line BC is,


Since AD is altitude to BC, we can say AD is perpendicular to BC, so the slope of the line AD which is perpendicular line to BC will be,

1. Let A(a,b) be a point in the coordinate axis. The reflection of A with respect to the x-axis is the point A'(a, -b).
2. So the reflection of C(6, 4) is C'(6, -4)
3. Remark, a picture is always helpful when dealing with reflections.
