The circle C cuts the x-axis at the points (2,0) and (10,0),where its centre R lies in quadrant I.It is given that the radius of C is 5 units.

Question:the equation of a straight line L is 4-3y+60=0.It si found that C and L do not intersect .Let P be the point lying on L such that P is nearest to R.

Let Q b a mobing point on C .Jackey claims that when Q is furest from P, the ratio of the area triangle OPQ to the area of triangle OQR is 5:1, where O is the origin . Do you agree? Explain your answer!

I've drawn the graph below - see if it helps (I've assumed you meant L to be 4x-3y+60=0).

Circle, line, triangle
