Q. What is the image point of (−6,−1) after the transformation R180 o ry=−x ?
Perform Rotation: The transformation R180quadr11x2 seems to be a combination of a rotation by 180 degrees and a translation. However, the notation is not standard. Assuming "R180" means rotation by 180 degrees around the origin and "quadr11x2" means translation by a vector, we need to clarify the translation vector. For the purpose of this solution, I will assume that the translation vector is (11,2). First, we will perform the rotation of the point (6,1) by 180 degrees around the origin.
Calculate New Coordinates: To rotate a point (x,y) by 180 degrees around the origin, the new coordinates become (−x,−y). So, the image of the point (6,1) after rotation by 180 degrees is (−6,−1).
Perform Translation: Next, we perform the translation using the vector (11,2). To translate a point (x,y) by a vector (a,b), we add the vector components to the point's coordinates, resulting in a new point (x+a,y+b). Therefore, we add (11,2) to the point (−6,−1).
Final Coordinates: Adding the translation vector (11,2) to the rotated point (−6,−1) gives us the new coordinates: (−6+11,−1+2)=(5,1).
