Explicação passo a passo:
[tex]\mathsf{d_{AB} = \sqrt{(x_A - x_B)^2 + (y_A - y_B)^2}}[/tex]
[tex]\mathsf{d_{AB} = \sqrt{(2 - (-1))^2 + (-6 - 0)^2}}[/tex]
[tex]\mathsf{d_{AB} = \sqrt{(2 + 1)^2 + (-6 - 0)^2}}[/tex]
[tex]\mathsf{d_{AB} = \sqrt{(3)^2 + (-6)^2}}[/tex]
[tex]\mathsf{d_{AB} = \sqrt{9 + 36}}[/tex]
[tex]\mathsf{d_{AB} = \sqrt{45}}[/tex]
[tex]\mathsf{d_{AB} = \sqrt{3^2.5}}[/tex]
[tex]\boxed{\boxed{\mathsf{d_{AB} = 3\sqrt{5}}}}[/tex]
