Replace x in the equation of the circle and solve for y.
i have 2 questions, the first one i could do, its the second i need help with. 1) determine the coordinates of the centre and the radius of the circle with equation . so i put it in its squared form (if thats what you call it. if not, any corrections would be appreciated) like so:
so the centre must be and the radius is 5
the second question which i need help with is:
find the coordinates of the points P and Q, where the line intersects this circle. could someone show me in detail the way you would answer this
thanks for any help
