Answer 3

if u are reflecting a point across y=c then x coordinate remains same
i.e., image of A(6, -4) after it is reflected over the line y = - 2 has x cordinate same(i.e.,6) where as y is (y-4)/2=-2=>y=0
for point (6,0) after it is reflected over x=1, y remains same as 0.
xis (6+x)/2=1 solve for x

Answer 4

so answer is (-4,0)

Answer 5

ah. thanks
