8 On a coordinate plane, consider the transformation of dilating a line by a factor of 3, with the point (0,8) as the center of
dilation. Which line remains unchanged under the transformation?
Select all that apply.
A The line y = 3x + 8
B The line y =3(2-8)
C The line'y = 3(x + 8)
D The line y = 4.3 + 8
E The line y = 4(3-8)
The line y = -3.2 + 8

Identify the graph of y = ln x + 1.
