parallel lines, have the same exact slope, hmmm what is the slope of y = -2/3 x + 1/3 anyway? well, low and behold, the equation is already in slope-intercept form, therefore


\bf ~~y=\stackrel{slope}{-\cfrac{2}{3}}x+\cfrac{1}{3}~~ has a slope of -2/3.


so we're really looking for a line whose slope is -2/3 and runs through 9,4.


\bf (\stackrel{x_1}{9}~,~\stackrel{y_1}{4})~\hspace{10em}slope =  m\implies -\cfrac{2}{3}\\\\\\\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-4=-\cfrac{2}{3}(x-9)\\\\\\y-4=-\cfrac{2}{3}x+6\implies y=-\cfrac{2}{3}x+10

Hello!

If we want a parallel line, it needs to have the same slope as the other line. If we look at our first equation, the slope of the line is -2/3. This gives us y=-2/3x+b

To finish our equation, we will want to find b. To do so, we can plug the point (9,4) in for (x,y) and solve for b.

4=-2/3(9)+b

4=-6+b

b=10

This gives us our equation below.

y= -2/3x+10

I hope this helps!

Answer:

Now we have everything in order to replace into formula (1):

18-2.262\frac{2.75}{\sqrt{10}}=16.03    

18+2.262\frac{2.75}{\sqrt{10}}=19.97    

Step-by-step explanation:

Information given

\bar X=18 represent the sample mean

\mu population mean (variable of interest)

s=2.75 represent the sample standard deviation

n=10 represent the sample size  

Confidence interval

The confidence interval for the mean is given by the following formula:

\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}   (1)

The degrees of freedom are given by:

df=n-1=10-1=9

The Confidence is 0.90 or 90%, the significance is \alpha=0.1 and \alpha/2 =0.05, and the critical vaue would be t_{\alpha/2}=2.262

Now we have everything in order to replace into formula (1):

18-2.262\frac{2.75}{\sqrt{10}}=16.03    

18+2.262\frac{2.75}{\sqrt{10}}=19.97

Since there aren't any like terms, you can't simplify it any more.
