Answer:
A) The point( -1 , 5) is satisfies the given graph 
B) The point( 3 , 1/125) is satisfies the given graph 
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given graph
y = 
Put the point ( -1 , 5)
Put y =5 and x =-1

The point( -1 , 5) is satisfies the given graph
ii)
Given graph
y = 

The point( 3 , 1/125) is satisfies the given graph 
It is not true because there C and E are on different sides, if that makes sense (which means your answer is correct)
Step-by-step explanation:
-5 × -5 = 25
-6 + 5 = 1
-3 + 5 = -8
The coefficient of determination can be found using the following formula:
![r^2=\mleft(\frac{n(\sum ^{}_{}xy)-(\sum ^{}_{}x)(\sum ^{}_{}y)}{\sqrt[]{(n\sum ^{}_{}x^2-(\sum ^{}_{}x)^2)(n\sum ^{}_{}y^2-(\sum ^{}_{}y)^2}^{}}\mright)^2](https://tex.z-dn.net/?f=r%5E2%3D%5Cmleft%28%5Cfrac%7Bn%28%5Csum%20%5E%7B%7D_%7B%7Dxy%29-%28%5Csum%20%5E%7B%7D_%7B%7Dx%29%28%5Csum%20%5E%7B%7D_%7B%7Dy%29%7D%7B%5Csqrt%5B%5D%7B%28n%5Csum%20%5E%7B%7D_%7B%7Dx%5E2-%28%5Csum%20%5E%7B%7D_%7B%7Dx%29%5E2%29%28n%5Csum%20%5E%7B%7D_%7B%7Dy%5E2-%28%5Csum%20%5E%7B%7D_%7B%7Dy%29%5E2%7D%5E%7B%7D%7D%5Cmright%29%5E2)
Using a Statistics calculator or an online tool to work with the data we were given, we get
So the best aproximation of r² is 0.861
