Remember that, by definition: , then you have:
Subtract 6 from both sides of the equation.
Then the value of x is:
Since eleven is odd, there must be a centra element, which in this case is the sixth. So, we can write 11 consecutive integers as
Since the arithmetic mean is the sum of the values, divided by how many they are, we have
So, the mean of 11 consecutive integers is the 6th integer.
Let be the line that passes through both points.
We know that and
. So:
Solving the system, we get that a= -1 and b = 6.
So the line is equal to .
