Answer: Last option.
Step-by-step explanation:
By definition, Inverse variation equations have this form:
Where "k" is the constant of variation.
In this case, it is:
Knowing that 
when 
, we can substitute values into the equation and solve for "k":
Therefore, we can find the value of "n" when 
by substiuting this value and the value of "k" into the equation and solving for "n". Then:
The answer is 7 because the mean is an average. So if you add up all the numbers and then divide that number by the amount of numbers listed then that will get you your answer which is 7
4+5+6+7+8+9+10=49
49/7=7

Answer: -6/5</h3>
Explanation:
The blue diagonal line goes through the two points (0,2) and (5,-4). These are shown as the dark blue enlarged points. You can pick any other points you want that are on the diagonal line, though these are the easiest as they stand out the most.
Use the slope formula to find the slope through these points
m = (y2-y1)/(x2-x1)
m = (-4-2)/(5-0)
m = (-6)/(5)
m = -6/5
The negative slope means the line goes downhill as you move from left to right along the diagonal line.
