Question 863330
{{{(3/4)sqrt((2-(-2))^2+(-3-(-1))^2)=sqrt((x-2)^2+(y-(-3))^2)}}}, the translation of the description and question into pure symbols.  Distance Formula is used.
{{{(3/4)sqrt((4)^2+(-2)^2)=sqrt((x-2)^2+(y+3)^2)}}}
{{{(3/4)sqrt(16+4)=sqrt((x-2)^2+(y+3)^2)}}}
{{{(9/16)*20=(x-2)^2+(y+3)^2}}}
{{{highlight_green(45/4=(x-2)^2+(y+3)^2)}}},  which is the equation of a circle.


You also want the line containing points E and F. 
Using slope-intercept form completely, y=mx+b, b=y-mx,
{{{m=(2+2)/(-2)=-2 }}};
{{{b=-3-(-2)2=1}}};
{{{highlight_green(y=-2x+1)}}}


The rest of the solution process is undone intentionally, so you could finish, or try to finish.
