Calculate the distance between two coordinates in 2D, where all the values are integers but at least one is negative Amy is trying to work out the distance between these two points: \( (2,-5) \) and \( (-7,1) \) She labels them like this: \( \begin{array}{cccc}x_{1} & y_{1} & x_{2} & y_{2} \\ (2, & -5) & (-7, & 1)\end{array} \) And then decides to use this formula: \( \sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}} \) What does the first bracket equal? \( (-5)^{2} \)
