Answer:
The correct choices are (-3,-1), (-3,2), (-5,3) and (-7,1)
Step-by-step explanation:
Given that MAST with coordinates M(-3,-1), A(-3,2),S (-1,3) and T(1,1).
The mapping for reflection across the line [tex]x=k[/tex] is
[tex](x,y)\to (2k-x,y)[/tex]
The coordinates of M'A'S'T'.
M'(2(-3)--3,-1), A'(2(-3)--3,2),S' (2(-3)--1,3) and T'(2(-3)-1,1)
M'(-6+3,-1), A'(-6+3,2),S' (-6+1,3) and T'(-6-1,1)
M'(-3,-1), A'(-3,2),S' (-5,3) and T'(-7,1)
