Question

The coordinates of a point on a coordinate grid are (−2, 6). The point is reflected across the x-axis to obtain a new point. The coordinates of the reflected point are
 (2, 6)                (−2, 6)             (−2, −6)           (2, −6)

If it reflects over the x-axis, that means the x-value stays the same (-2).  The y-value would change to the opposite of what it currently is (from 6 to -6).  There's a (messy) picture below.  When you reflect across an axis, you move the point the same number of steps on the other side of the axis.  In this case, it took 6 steps to move down to the x-axis, so we take 6 more steps away from the x-axis (below) -- taking us to the point (-2, -6)
