Answer: 40?
Step-by-step explanation: I don't quite understand your question fully
No. If you plug in the points, you have 2=5(4). 2=20 is not true, so it does not satisfy it

can also be written as 2i
where i = √-1

Rationalizing denominator,
This your answer hope i helped. :)
<span> The point lies one unit above the regression line. </span>
Answer:
See below.
Step-by-step explanation:
So we started off with the equation:

And we subtracted x from both sides to acquire:

Now, this is essentially slope-intercept form. Recall that the slope-intercept form is:

Where m is the slope and b is the y-intercept.
If we rearrange our equation:

And put some parentheses:

We can see that this is indeed slope-intercept form.
And we can see that m is -1 and b is 2.
In other words, the slope is -1 and the y-intercept is 2.
