In the plane, Ine kis parallel to the line with equation y = 7x + 5 . Which of the following could be an equation of line k?
2 answers:
Answer:
see the explanation
Step-by-step explanation:
we know that
If two lines are parallel, then their slopes are the same
In this problem we have
This is the equation of a line in slope intercept form
where
---> is the slope
---> is the y-intercept
therefore
Any equation with a slope 7 and y-intercept different of 5 could be the equation of the line k
Note If the slope is 7 and the y-intercept is 5 we have identical lines not parallel lines

Hello!
You need to construct a 95% CI for the population mean of the length of engineering conferences.
The variable has a normal distribution.
The information given is:
n= 84
x[bar]= 3.94
δ= 1.28
The formula for the Confidence interval is:
x[bar]±*(δ/n)
Lower bound(Lb): 3.698
Upper bound(Ub): 4.182
Error bound: (Ub - Lb)/2 = (4.182-3.698)/2 = 0.242
I hope it helps!
