Pre-image point N(6,-3) was dilated to point N'(2, -1). What was the scale factor used?

scale factor =

Step-by-step explanation:

Consider the ratio of the x and y- coordinates, image to original, that is

scale factor = = =

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
