To simplify this, you would have to turn b^-2 into a positive exponent. To do this, we have to flip b^-2, which would get rid of the negate from the exponent: -2
3a^4 b^-2 c^3 / b^-2
Then we get the answer:
3a^4 c^3 ------------ b^-2
I have a picture to clarify! I hope this helped, let me know if you don't understand! ^.^
The answer is B because first u subtract 3y from both sides and then subtract 15 from both and then divide both sides by -5 and u’ll have y=-5/3x+5 so -5/3 is the slope
