Ответ: (6.5;0)

Объяснение:

Пусть это точка М

М= ((Xa+Xa1)/2; (Ya+Ya1)/2)= ((2+5)/2 ;(3+1)/2) = (3.5; 2)

Пусть при параллельном переносе М переходит в М1

Тогда координаты векторов АА1 и ММ1 равны (равны и сами вектора)

Найдем координаты АА1 = (Xa1-Xa ; Ya1-Ya)  =(5-2; 1-3) =(3; -2)

Тогда координаты ММ1= (Xm1-Xm; Ym1-Ym)= (3;-2)

=> Xm1= 3+Xm=3+3.5 =6.5

Ym1=-2+Ym = -2+2=0

Итак М перейдет в точку М1 с координатами (6.5;0)
