Question 1071037
The ratio shows 3+2=5 parts.


Going from A to C taking 3 of these equal parts,
Uses a {{{3/5}}} point formula (that fraction instead of "midpoint" formula).


{{{(x-6)/(3/5)=3.6}}}
{{{x-6=(3/5)(3.6)}}}
{{{x=6+3*3.6/5}}}
{{{x=8.16}}}
-
{{{(y+5)/(3/5)=-0.4}}}
{{{y+5=-0.4(3/5)}}}
{{{y=-5-0.4(3/5)}}}
{{{y=-5.24}}}
-
The endpoint B is  (8.16,-5.24).
