y = -7x + 1
y = -7(0) +1
y = 1
Out of that particular list, the only description
that applies to 2.5 is "rational".
It's 10 - 4
moving decimal over to the right makes a negative exponent.
We can do this by just adding 14 to 14 until we get a number that is divisible by 10. We can do it this way because it will be a small number. Let's list them out. 14, 28, 42, 56, 70. 70 is divisible by 10, so 70 is the answer.
