The graph below is a scatter plot with 20 points, each representing

1.
2 of the coldest cities are lying below the horizontal line of 8
One dot is near to the vertical line of 100 and the other dot is near to the vertical line of 200.

We can consider the dots on 100 and 200 respectively.

200 = 100 (1+\(\frac{x}{100}\))
2 = \(\frac{100+x }{ 100}\)

200 = 100 + x
X = 100%

Answer D

2.
The relationship between average temperature and elevation is Zero

Comparing the dots in the higher elevation region of the graphs with the dots in the lower elevation region of the graphs, there are certainly fewer dots in the higher elevation region, but the dots in the higher elevation region are parallel (nearly parallel) to some of the dots in the lower elevation region.
So, there is negligible change/zero change.
