Find algebraically the coordinates A and B show that the distance AB is sqrt 162 and the previous qs asks about radius and centre of the circle

Best ResponseYou've already chosen the best response.0Put the two equations together, you would find to values for y=3, y=34. You can use these values to obtain related values for x. The two x,y values should be point A and B. You can double check it with distance formula.

Best ResponseYou've already chosen the best response.0sorry but i dont understand? :S so do i put those two values into the equation??

Best ResponseYou've already chosen the best response.0You have your equation for the line, you can solve for x, or y. From your line equation, x=3y. Put this in the circle equation. (3y)^2+y^2=45. I have already done this much for you, the result is y=3, y=34

Best ResponseYou've already chosen the best response.0Well forget about 3 and 34. Solve for y from the new equation created.
