Among the statements (S1) : If A$\displaystyle (5, -1)$ and B$\displaystyle (-2,3)$ are two vertices of a triangle, whose orthocentre is $\displaystyle (0, 0)$, then its third vertex is $\displaystyle (-4, -7)$ and (S2) : If positive numbers 2a, b, c are three consecutive terms of an A.P., then the lines $\displaystyle \mathrm{a} x+\mathrm{by}+\mathrm{c}=0$ are concurrent at $\displaystyle (2, -2)$,
