Here we are supposed to find the distance between the two points
Suppose A=(-8,-9), B=(-4,-10)
Now As per the distance formula we know that the distance between two points is given by the formula
[tex] D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\
\\
D= \sqrt{(-4+8)^2+(-10+9)^2}\\
\\
D=\sqrt{(4)^2+(-1)^2}\\
\\
D=\sqrt{16+1}\\
\\
D=\sqrt{17} \ miles [/tex]
