Answer:
[tex] \sqrt{113} [/tex]
Step-by-step explanation:
(-9, -1), (-1, 6)
x1 = -9
x2 = -1
y1 = -1
y2 = 6
[tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
[tex]d = \sqrt{(-1 - (-9))^2 + (6 - (-1))^2}[/tex]
[tex]d = \sqrt{8^2 + 7^2}[/tex]
[tex]d = \sqrt{64 + 49}[/tex]
[tex]d = \sqrt{113}[/tex]
