Answer: The last expression shows the result of 3 so it models the distance between x and y.

Explanation:

First you will have to find the distance between the two points by square the x coordinates and squaring the y coordinates to find their sum .

-4 - (-1) = -3

-5 - ( -5) = 0

-3^2 + 0^2 = d^2 where d is the distance

9 = d^2

d= 3

The distance is 3 units

Now evaluate which expression have a solution as 3.

The last expression is the answer

the absolute value for -4 is 4 , and the absolute value for -1 is 1 and 4 minus 1 is 3.
