What is the rule for finding the reflection of a point over the axis?
For a reflection over the x axis, leave the x coordinate unchanged and change the sign of the y coordinate.For a reflection over the y axis, leave the y coordinate unchanged and change the sign of the x coordinate.

What is the algebraic rule for a figure that is rotated 270 clockwise about the origin?
When a figure is rotated 270 degrees clockwise about the origin, the algebraic rule for the transformation of a point ((x, y)) is given by ((x, y) \rightarrow (y, -x)). This means the x-coordinate takes the value of the y-coordinate, and the y-coordinate becomes the negative of the original x-coordinate.
What does reflection over the y-axis mean?
Example: if you have a point with the coordinates (2,4), a reflection over the y-axis will result in the point with coordinates (-2,4).

What transformation gives the same result as a rotation of 180 around the origin followed by a reflection over the y axis?
A rotation of 180 degrees around the origin followed by a reflection over the y-axis is equivalent to a single transformation: a reflection over the x-axis. This is because the 180-degree rotation negates both the x and y coordinates, and the subsequent reflection over the y-axis negates the x-coordinate again, resulting in a reflection over the x-axis.
What is the rule for a reflection across the origin followed by a translation 3 units to the right and 4 units up?
A reflection across the origin transforms a point ((x, y)) to ((-x, -y)). After this reflection, a translation of 3 units to the right and 4 units up shifts the point to ((-x + 3, -y + 4)). Therefore, the combined rule for the transformation is given by the mapping ((x, y) \to (-x + 3, -y + 4)).
