Vedclass · Answer

(A) point of the form $(a, -a)$ has an $x$-coordinate equal to $a$ and a $y$-coordinate equal to $-a$.To find the line on which this point lies,we can observe the relationship between the coordinates:$x = a$$y = -a$Adding these two equations gives:$x + y = a + (-a)$$x + y = 0$Therefore,the point $(a, -a)$ always satisfies the equation $x + y = 0$.

The point of the form $(a, -a)$ always lies on the line
