Answer:

(-4,-3)

Step-by-step explanation:

we know that

The distance OB is equal to

(8-4)=4 units

To find the new distance OB', multiply the distance OB by the scale factor

so

OB'=OB*3

OB'=4*3=12 units

The x-coordinate of point B' is equal to

8-12=-4

The y-coordinate of point B' is the same that B  -3

the coordinates of point B'are (-4,-3)

Answer:

-4,-3
