Answer:
y = -2/3x - 3
Step-by-step explanation:
y = -2/3x + b
-1 = -2/3(-3) + b
-1 = 2 + b
-3 = b
y = -2/3x - 3
√- 81 doesn't result in a rational number because you can't get a negative from squaring any number. Instead you get a number with an imaginary number.
13 - √- 81 = 13 - 9i

<em><u>Solution:</u></em>
Given that,

<em><u>Use the following log rules</u></em>
Rule 1: 
Rule 2: 
Rule 3: 

Break 162 down to primes:


Thus we get,

Next

Break 324 down to primes:


Next

By rule 2

Next

By rule 2

Thus the given are evaluated in terms of x and y
y=2x-1....
I think that's the answer
