Question

Q. 8 : Locate the following points on the Cartesian plane (Where (a in R)) (1) (o, a) (ii) (a, 0) iii)(-a,o) (iv) (0, - a)​

Answer 1

Answer:

of the circle ? coordinate geometry ... PA2 = PB2 = PC2 = r2. ⇒ (x – 1)2 + (y – 7)2 = r2 … (i). (x – 7)2 + (y + 1)2 = r2 ….(ii) ... (x2 + 1 – 2x + y2 + 49 – 14y) – (x2 + 49 – 14x + y2 + 1 + 2y) = 0 ... From (iv) y = 3/4x = ¾ × 4. Y = 3 ... The centre 'O' of a circle has the coordinates (4, 5) and one point on the circumference is (8, 10).
