Question 947263
So then point R is {{{1/(1+5)=1/6}}} of the way from E to F.
The distance in x from E to F is 7. 
So {{{7/6}}} from E is {{{4+7/6=24/6+7/6=31/6}}}
The distance in y from E to F is -4. 
So {{{-4/6=-2/3}}} from E is {{{8-2/3=24/3-2/3=22/3}}}
So then
R=({{{31/6}}},{{{22/3}}})
You can work it out to 2 decimal places.
