20 points and brainliest! asap, absolute value with explanation pls

I think the answer is A. If you use the values for each variable approximately a(2.2) or b(8.5) or c(3.7). You will find that the only way to get a number greater than the value of "a" is to have a value that is fairly high. Thus, if you substitute my values into the equation you will see that the answer is greater than "a". Hope this helped :))

what's that

its a straight line parallel to the time axis
