yes
no
submit

Explanation:

Step1: Identify x and y values

From the point \((9, -9)\), we have \(x = 9\) and \(y=-9\).

Step2: Substitute into the equation

The equation is \(y=-x\). Substitute \(x = 9\) into the right - hand side: \(-x=-9\). And the left - hand side \(y=-9\). Since the left - hand side (\(y=-9\)) is equal to the right - hand side (\(-x=-9\)) when \(x = 9\), the point \((9,-9)\) satisfies the equation \(y = -x\).

Answer:

yes
