Correct Answer: Option A
Explanation:
L\(\begin{pmatrix} x_1 & y_1 \\ -1 & -6 \end{pmatrix}\) m L\(\begin{pmatrix} x_2 & y_2 \\ -3 & -5 \end{pmatrix}\)
D = \(\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\)
D = \(\sqrt{(-3 - (-1)^2 + (-5 -(-6)^2}\)
D = \(\sqrt{(-3 + 1)^2 + (-5 + 6)^2}\)
D = \(\sqrt{(-2)^2 + 1^2}\)
D = \(\sqrt{4 + 1}\)
D = \(\sqrt{5}\)
L\(\begin{pmatrix} x_1 & y_1 \\ -1 & -6 \end{pmatrix}\) m L\(\begin{pmatrix} x_2 & y_2 \\ -3 & -5 \end{pmatrix}\)
D = \(\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\)
D = \(\sqrt{(-3 - (-1)^2 + (-5 -(-6)^2}\)
D = \(\sqrt{(-3 + 1)^2 + (-5 + 6)^2}\)
D = \(\sqrt{(-2)^2 + 1^2}\)
D = \(\sqrt{4 + 1}\)
D = \(\sqrt{5}\)
