[tex]C(-5, -3), \ \ D(-4, -2)\\ \\ Distance \ Formula:\ Given \ the \ two \ points \ (x _{1}, y _{1}) and (x _{2}, y _{2}), \\ \\the \ distance \ between \ these \ points \ is \ given \ by \ the \ formula: \\ \\ d= \sqrt{(x_{2}-x_{1})^2 +(y_{2}-y_{1})^2} \\ \\d=\sqrt{( -4-(-5))^2 +(-2-(-3))^2}\\ \\d=\sqrt{( -4+5)^2 +(-2+3)^2}\\ \\d=\sqrt{1^2 + 1^2}\\ \\d= \sqrt{1+1}=\sqrt{2} \approx 1.4[/tex]
