In a standard (x,y) coordinate plane, point M is located at (-4 1/2, 18 1/3) and N is located at (-4 1/2, -2 2/3.) Find the length of segment NM.

Answer:
[tex] \frac{ - 9}{2} + \frac{9}{2} = 0[/tex]
[tex] \frac{55}{3} + \frac{8}{3} = \frac{63}{3} [/tex]
[tex] \sqrt{ {0}^{2} + \frac{ {63}^{2} }{3} } = \sqrt{ \frac{3969}{9} } = \frac{63}{3} [/tex]
this is the
