POINT A: (4,-12)
POINT B:(8,-16)
determine the scale factor used in the dilation of the line segment AB, centered at the origin.
answer choese are
a.4
b.2
c.-4
d. 1/4
To find the scale factor used in the dilation of the line segment AB centered at the origin, we need to calculate the ratio of the changes in the x and y coordinates.
The change in x coordinates is 8 - 4 = 4.
The change in y coordinates is -16 - (-12) = -4.
Therefore, the scale factor is 4/-4 = -1.
So the correct answer is c. -4.
