The graph of the line \(y=-x\) must pass through which of the following points?

Answer and explanation

Correct answer: (3,-3)

For the point \((3,-3)\), \(x=3\) and \(y=-3\), so it satisfies \(y=-x\). In option A, when \(x=3\), the value of \(y\) should be \(-3\), not \(3\), so it is incorrect. As an exam tip, substitute the coordinates directly into the equation; every point on this line satisfies \(x+y=0\).
