Suppose you have line ab on a coordinate plane located at a(-3,-4) and b(5,-4). under a dilation centered at (9,0), line ab becomes like a' b' with coordinates a'(6,-1) and b'(8,-1). what is the scale factor for this dilation?

Step-by-step explanation:

Center of dilation: O(9,0).

Line AB with A(-3,-4) and B(5,-4) is dilated with the scale factor k and center of dilation at O to form line A'B' with A'(6,-1) and B'(8,-1).

Then

Since

then

i believe the correct answer is b.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
