The distance between two points is:
d = √(([tex]x_{2}[/tex]-[tex]x_{1}[/tex])²+([tex]y_{2}[/tex]-[tex]y_{1}[/tex])²)
d = distance, ([tex]x_{1}[/tex], [tex]y_{1}[/tex]) = start coordinate, ([tex]x_{2}[/tex], [tex]y_{2}[/tex]) = end coordinate
Given values:
([tex]x_{1}[/tex], [tex]y_{1}[/tex]) = (2, -9)
([tex]x_{2}[/tex], [tex]y_{2}[/tex]) = (-1, 4)
Plug in and solve for d:
d = √((-1-2)²+(4-(-9))²)
d = √(9+169)
d = 13.3
