PLEASE HELP MEE. The equation of a line is y=-1/2x-2 What is the equation of the line that is perpendicular to the first line and passes through the point (2, –2)? A. y = 2x – 2 B. y=1/2x-3 C. y = 2x – 6 D. y = –2x + 2

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.
