Answer 5

Step 2 results in (5,-1). Try to figure out the last part (180 deg rotation).

Answer 6

@slumberousteenager, of course the entire parallelogram rotates. But in this case, we only need to keep track of point A. There are three transformations. A reflection over the y-axis, a reflection over the x-axis and a 180 degree rotation. When point A reflects over the y-axis it resides in quadrant 1. When A reflects over the x-axis, it resides in quadrant 4. When A gets reflected over the origin (180 degrees) it returns back to the 2nd quadrant.
