![\bf \stackrel{a}{-8}\stackrel{b}{-17}i\qquad \qquad \stackrel{a}{3}\stackrel{b}{+b}i \\\\\\ \textit{so let's use those two points of (-8, -17) and (3,b)} \\\\\\ \textit{distance between 2 points}\\ \quad \\ \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) &({{ -8}}\quad ,&{{ -17}})\quad % (c,d) &({{ 3}}\quad ,&{{ b}}) \end{array}\qquad % distance value d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2} \\\\\\ \stackrel{61}{d}=\sqrt{[3-(-8)]^2+[b-(-17)]^2}\implies 61=\sqrt{(3+8)^2+(b+17)^2}](/tpl/images/0042/1862/01ee4.png)
