The first statement is false and answer to second statement is no.
The mentioned information does not state that x and y are linearly related or not. If they are not related in linear way, the mean value of y would not be located at the mean of the x values.

Answer:
The last one in the bottom. h = 24
Step-by-step explanation:
As i see this problem, we need to find the missing leg of this right triangle.
But first lets find the hypotenuse of the other triangle.
a^2 + b^2 = c^2
10^2 + 6^2 = c^2
c = root of 136
The proportion is 1 to 4, so now we can find the longest hypotenuse.
root of 136 * 4 = 32
And now we can find the height of the tree.
root of 32^2 - 40^2 = h^2
h = 24
I have solved this problem not using a proportion, but I can say that the last answer will be the right answer.
