To find the slope, use the equation: m = y2 - y1 / x2 - x1
Hope this helps!
Answer:
That the Sun was the center of the universe.
Explanation:
Ptolemy believed in geocentrism, which means that the Earth is the center of the Universe. This was also supported by Aristotle. Copernicus on the other hand believed in a heliocentric system, which proposes that the sun is the center of the universe.

And while reversals have happened more frequently in "recent" years, when ... per year, as opposed to about 10 miles per year in the early 20th century.
Explanation:
The human is a pedestrian
For this problem, we use the decay equation which is expressed as:
An = (Ao)e^-kt
where An is the amount left in t time, Ao is the initial amount and k is a constant.
We first calculate the value of k as follows:
An = (Ao)e^-kt
0.5 = e^-k(8)
k = 0.087
We calculate the time as follows:
An = (Ao)e^-kt
15.625 = 250e^-0.087t
t = 31.87 days
