Let pint B be (1,2)
Mid point A (-3,6)
Difference in x coordinate between point B and A is 4
Difference in y coordinate between point B and A is 4
Since A is midpoint, the distance between the point c(x1,y1) will same as the distance between point B and A.
Hence x1 = -7 (4 units away from x cordinate of point B)
y1 = 10
Poinnt C = (-7,10)
