Which lines are perpendicular to the line y – 1 = 1 (x+2)? Check all that apply.
y+ 2 = -3(х – 4)
у – 5 = 3(х + 11)
Y= -3х – 5/3
у= 1/3х - 2
3х + y = 7

step-by-step explanation:

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

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