Question

Professor PC Thomas Classes · Answer

(a) : The point $(0,0)$ is the midpoint of $A(-a,-b)$ and $B(a, b)$.\ $	herefore A, O, B$ are collinear and equation of $A O B$ is $y=\frac{b}{a} x$\ $D=\left(a^{2}, a bight)$ satisfies the equation of $A O B$\ $	herefore \quad$ The four points are collinear.\
