Given:
1st point (5,8)
2nd point (7,10)
3rd point (9,12)
4th point (11,14)

After transformation, the sing of the x-coordinate for each ordered pair has changed. From positive, it becomes negative. However, the sign of the y-coordinate is assumed to retains its original sign.

From positive x and positive y to negative x and positive y, this is C. REFLECTION ACROSS THE Y-AXIS.
