the difference between "k" and "g" is also the distance between them

thus
\bf \textit{distance between 2 points}\\ \quad \\ \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) k&({{ -2}}\quad ,&{{ -1}})\quad % (c,d) g&({{ 2}}\quad ,&{{ 8}})\\\\ \end{array}\qquad % distance value d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}\\\\ -----------------------------\\\\ kg=√([2-(-2)]^2+[8-(-1)]^2)
