AB is a reduction of A′B′ by a scale factor of 1/2. (Equivalently, A′B′ is an enlargement of AB by a factor of 2.)

The center is the origin and the scale factor is 1/2, so (x,y) → (x/2,y/2). From the graph A = (2,4) and B = (6,6). Thus A′ = (2/2, 4/2) = (1,2) and B′ = (6/2, 6/2) = (3,3). Check lengths: AB = sqrt((6−2)^2+(6−4)^2) = sqrt(16+4) = 2√5, and A′B′ = sqrt((3−...

Electronegativity decreases down a group, and reactivity increases down a group. Reason: Atomic size and shielding increase down a group, lowering electronegativity and ionization energy, so metals more readily lose electrons (become more reactive).
