Write y - 4 = 1 ( x - 4) in slope intercept form.

y=x

Step-by-step explanation:

First, distribute the 1 to the x and -4. Both of these when multiplied by one equal their original value, leaving you with y-4=x-4.

Then, to isolate the y, you add 4 to both sides. This leaves you with simply y=x.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
