Answer:
Explanation:
(9). Reflection across the x-axis keeps the same x-coordinate and y-coordinate is the opposite to original ( x , y ) ------> ( x , - y )
(10). Reflection across the y-axis keeps the same y-coordinate and x-coordinate is the opposite to original ( x , y ) ------> ( - x , y )
(11). Translation along the vector < 0, 2 > means that each point of triangle moves 2 units UP ( x , y ) ------> ( x , y + 2 )
(12). Translation along the vector < 3, - 4 > means, that each point of triangle moves 3 units to the RIGHT and 4 units DOWN ( x , y ) ------> ( x + 3 , y - 4 )
(13). ( x , y ) ------> ( - x , - y )
(14). ( x , y ) ------> ( - y , x )
