Answer:

(1.0)

Explanation:

we know that

The scale factor of the dilation is 0.25 ----> given problem

The coordinates of point A(-5,-3) and F(3,1)

step 1

Find the x-coordinate of point A'

The horizontal distance between A and F is equal to

AFx=3-(-5)=8

The horizontal distance after dilation between A'F is equal to

A'F=0.25*8=2

so

the x-coordinate of vertex A' is equal to the x-coordinate of F minus the horizontal distance after dilation A'F

A'x=3-2=1

step 2

Find the y-coordinate of point A'

The vertical distance between A and F is equal to

AFy=1-(-3)=4

The vertical distance after dilation between A'F is equal to

A'Fy=0.25*4=1

so

the y-coordinate of vertex A' is equal to the y-coordinate of F minus the vertical distance after dilation A'F

A'y=1-1=0

therefore

The coordinates of vertex A of the image is (1.0)
