It is the second answer:
8x²/y -2 is a solution which is equivalent to (8x²-2y)/2. Proof:
Reduce 8x²/y -2 to the same denominator:
8x²/y - 2y/y = (8x² - 2y)/y
36÷4. 4 goes into 36, 9 times. Do your check work, which would be 9x4=36√. Hope that helps!
If they do not have a line of best fit this may be because there is no correlation
I believe the answer is 42 % which would be .42
