Since you mentioned the fundamental counting principle, I assume you are looking for the total number of possibilities.
If you are picking a month, there are 12 options.
If you are selecting a day of the week, there are 7 options.
If you are doing both, you multiply the two numbers together.
12 x 7 = 84
<h3>Hm ok, so the correct answer here would be (0,3) and heres why:</h3>
If the y would be equal to 0, everything would then just depend if you add or subtract the x:
Now the first answer could be correct for:
However, this answer is not correct for the other equation. the same true for all the other answers except (0,3)
