Answer:
B
Step-by-step explanation:
Use the distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Let (-1,-3) be [tex]x_1[/tex] and [tex]y_1[/tex], while (11,-8) be [tex]x_2[/tex] and [tex]y_2[/tex].
Thus:
[tex]d=\sqrt{((11)-(-1))^2+((-8)-(-3))^2[/tex]
[tex]d=\sqrt{12^2+(-5)^2}[/tex]
[tex]d=\sqrt{144+25} =\sqrt{169} =13[/tex]
