Plotting the data (attached photo) roughly shows that the data is skewed to the left. In other words, data is skewed negatively and that the long tail will be on the negative side of the peak.
In such a scenario, interquartile range is normally the best measure to compare variations of data.
Therefore, the last option is the best for the data provided.

ANSWER
The rule is given by the relation,
EXPLANATION
We need to check and see if there is a constant difference between the y-values.
We can see that, there is a constant difference of 2.
This means that the table represents a linear relationship.
Let the rule be of the form,
Then the points in the table should satisfy the above rule.
So let us plug in
This implies that,
Our rule now becomes,
We again plug in another point say, (-1,-1) in to equation (1) to get,
we solve for m now to obtain,
We now substitute back in to equation (1) to get

Answer:
Step-by-step explanation:
We know that one of the endpoints of the line segment is (x+4, 1/2y)
The midpoint of the line segment is (3, -2).
And we want to find the other coordinates in terms of x and y.
To do so, we can use the midpoint formula:
Since we know that the midpoint is (3, -2), let's substitute that for M:
Let's solve for each coordinate individually:
X-Coordinate:
We have:
We know that one of the endpoints is (x+4, 1/2y). So, let's let (x+4, 1/2y) be our (x₁, y₁). Substitute x+4 for x₁. This yields:
Solve for our second x-coordinate x₂. Multiply both sides by 2:
Subtract 4 from both sides:
Subtract x from both sides. Therefore, the x-coordinate of our second point is:
Y-Coordinate:
We have:
Substitute 1/2y for y₁. This yields:
Solve for y₂. Multiply both sides by 2:
Subtract 1/2y from both sides. So:
Therefore, the other coordinate expressed in terms of x and y is:
