To find distance between points <span>A(<span>xA</span>,<span>yA</span>)</span> and <span>B(<span>xB</span>,<span>yB</span>)</span>,
formula:
<span>d(A,B)=</span>√ [(xB−xA)^2+(yB−yA)^2]
so distance between the points: (–6, 7) and (–1, –5)<span>
</span>= √ [<span><span><span><span>(<span>−1−<span>(<span>−6</span>)</span></span>)^</span>2 </span>+ <span><span>(<span>−5−7</span>)^</span>2]
</span></span>= </span>√ (<span><span>25+144)
</span>= </span>√ 169
