How do you look for the center of the circle for this problem?
"Passing through P(5, -4) with R(-23/5, -8) being the point 1/5 of the way from the center to P."

I got the radius already (13 units), by getting the distance of P & R, then equating it to 4/5r. so r=13. But how do I get the center?

Thank you! :)
God bless

Reword:
"R(-23/5, -8) being the point 1/5 of the way from the center to P" $\rightarrow$ "the point 1/5 of the way from P to the center"

Would you said this sketch is what it's describing?

If (x,y) for R is (-4.6,-8), you're only a fifth of the way to the outer edge of the circle or visa-versa and the radius is 13 (going from what you said) wouldn't that mean...
