Question

More geometry help :)

Answer 1

see explanation

Explanation:

Assuming the dilatation is centred at the origin, then multiply each ot the coordinates by the scale factor 8

A (- 3, 2 ) → A' (8(- 3), 8(2) ) → A' (- 24, 16 )

B (2, 1 ) → B' (8(2), 8(1) ) → B' (16, 8 )

C (- 1, - 3 ) → C; (8(- 1), 8(- 3) ) → C' (- 8, - 24 )

Answer 2

Explanation:

Multiply both the co-ordinates of each vertex by the scale factor and then simplify it.

A(-3 , 2) A'(-3*8 , 2 * 8) = A' (-24 , 16)

B(2,1) B'(2*8 , 1*8) = B'(16,8)

C(-1,-3) C'(-1*8,-3*8)= C'(-8,-24)
