The critical value of r is mathematically given as r = +0.487, with no significant linear correlation. Option A.
<h3>What are the critical values of r?</h3>
Question Parameters
r = -0.868
n = 5
df = 5 - 2
df = 3
![\alpha / 2 =0.025](https://tex.z-dn.net/?f=%5Calpha%20%2F%202%20%3D0.025)
Critical values ![r= \pm 0.878](https://tex.z-dn.net/?f=r%3D%20%5Cpm%200.878)
Generally, there exists no linear correlation between the Critical values
as r=0.878
In conclusion, Critical values: r = +0.487, no significant linear correlation

Answer:
![y=-x+1](https://tex.z-dn.net/?f=y%3D-x%2B1)
Step-by-step explanation:
step 1
Find the slope
The formula to calculate the slope between two points is equal to
![m=\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
we have
(2,-1) and (-4,5)
substitute the values
![m=\frac{5+1}{-4-2}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B5%2B1%7D%7B-4-2%7D)
![m=\frac{6}{-6}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B6%7D%7B-6%7D)
![m=-1](https://tex.z-dn.net/?f=m%3D-1)
step 2
Find the equation of the line in point slope form
![y-y1=m(x-x1)](https://tex.z-dn.net/?f=y-y1%3Dm%28x-x1%29)
we have
![m=-1](https://tex.z-dn.net/?f=m%3D-1)
![point\ (2,-1)](https://tex.z-dn.net/?f=point%5C%20%282%2C-1%29)
substitute
![y+1=-(1)(x-2)](https://tex.z-dn.net/?f=y%2B1%3D-%281%29%28x-2%29)
![y+1=-(x-2)](https://tex.z-dn.net/?f=y%2B1%3D-%28x-2%29)
step 3
Convert to slope intercept form
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
isolate the variable y
![y+1=-x+2](https://tex.z-dn.net/?f=y%2B1%3D-x%2B2)
![y=-x+2-1](https://tex.z-dn.net/?f=y%3D-x%2B2-1)
![y=-x+1](https://tex.z-dn.net/?f=y%3D-x%2B1)
