x coordinate is reduced by 7; y coordinate is increased by 7
so transformation is (x,y) -> (x-7, y+7)
applying the same transformation to B(3,7)
B' = (3 - 7, 7 + 7) = (-4,14)

case (i). Find translation factor. T (a,b) A(x,y)=A(x,y)+ T(a,b) A'(-2,3)=A(5,-4) + T(a,b) T(a,b)={(-2-5),(3+4)} T(a,b)= (-7,7) transaltion factor is T(-7,7) Case (ii) let (3,7) be A(n,m) A''(x,y)=A(n,m)+ T(a,b) A''(x,y)=A(3,7) +T(-7,7) A"(x,y)=(-4,14)05/20/22
