The answer is going to be C. y = 2x – 6. This is because its the only line that is perpendicular and intersects through (2,–2) however B and D also pass through this point they are not perpendicular Because they are not at a 90 degree angle with the other line. Desmos graphing calculator is really helpful I suggest you use it It was what got me through hi school with ease.
