A negative times a negative is a positive. I am not sure if that's the question, but hopefully that helps if it was.
I don’t know the answer but Don’t try to open that link. I’ve seen a lot of people using it. Stay safe:)
The buyer will be paying taxes for 185 days, so will pay
... (185/365)·$8200 = $4156

There are 30 days in each month in the last half of the year, plus 1 additional day in each of July, August, October, and December. The 30th of June also belongs to the buyer (but the 29th, closing day, does not), so there are 180+5 = 185 days for which the buyer must pay taxes. The answer choices don't include that value.
This equation would be equal to y = -5x + 30
