The procedure to find each point is

 

[ Vertex point of triangle - dilation center ] * scale factor + dilation center

 

First point

[ (-3,7) - (5, - 5) (1/4) + (5, -5)

[ -8, 12)(1/4) + (5, -5)

(-2, 3)  + (5, -5)

(3, -2)

 

Second point

[ (-7, -5) - (5, -5) ] (1/4) + (5, -5)

[ -12, 0 ] (1/4) + (5, -5)

(-3, 0) + (5, -5)

(2, - 5)

 

Last point

[ (9, 3)  - (5, -5) ] (1/4) + (5, -5)

[ 4, 8]  (1/4)  + (5, -5)

(1, 2)  + (5, -5)

(6, - 3)
