The formula of find the slope is -0.4285
use y2 - y1 over x2-x1
To simplify the rational expression, we are going to perform long division as you can see in the picture.
We can conclude that the quotient of the division is
(x+2) and the remainder is
6.
You know the y intercept is 4
The slope is 1/2
The equation is y = 1/2x + 4
Answer: 8
Step-by-step explanation:
The formula to find the t-test statistic for differences between in two population mean:-
![t=\dfrac{x_{1}-x_2}{SE}](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7Bx_%7B1%7D-x_2%7D%7BSE%7D)
,where
= sample mean difference
SE= Sample error
Given : SE= 4 points
t-statistic = 2.00
Substitute theses values in the above formula , we get
![2=\dfrac{x_{1}-x_2}{4}\\\\\Rightarrow\ x_{1}-x_2= 4\times2=8](https://tex.z-dn.net/?f=2%3D%5Cdfrac%7Bx_%7B1%7D-x_2%7D%7B4%7D%5C%5C%5C%5C%5CRightarrow%5C%20x_%7B1%7D-x_2%3D%204%5Ctimes2%3D8)
Hence, the sample mean difference is ![x_{1}-x_2= 8](https://tex.z-dn.net/?f=x_%7B1%7D-x_2%3D%208)
