Question

does the point (1, -1) satisfy the equation y = -x? yes no submit

Explanation:

Step1: Identify x and y values

For the point \((1, -1)\), \(x = 1\) and \(y=-1\).

Step2: Substitute into the equation

The equation is \(y=-x\). Substitute \(x = 1\) into the right - hand side: \(-x=-1\). And the left - hand side \(y = - 1\). Since the left - hand side (\(y=-1\)) is equal to the right - hand side (\(-x=-1\)) when \(x = 1\), the point \((1,-1)\) satisfies the equation \(y = - x\).

Answer:

yes
