The question requires you to find the distance between points A and B
Point A {-4,-1} and B {5,0}
Apply the formula for length between two points given coordinates;
[tex]d=\sqrt[]{(x_{2-x1)^2\text{ +}(y2-y1)^2}_{}}[/tex]
Use the values in the equation as;
[tex]d=\sqrt[]{(5--4)^2+(0--1)^2}[/tex]
This will give the following;
[tex]d=\sqrt[]{9^2+1^2}[/tex][tex]d=\sqrt[]{81+1}[/tex][tex]d=\sqrt[]{82}\text{ units}[/tex]
Answer : D
