Need ! (giving a lot of points)find the equation of the line that is perpendicular to the given line and passes through the given point. y = − 1/3x-9; (15, 0)show work

Try this option (the way shown is not the shortest one).

Change the design according to the local requirements.

y=3x-45

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
