It is an anticlockwise rotation through 90 degrees.

y + 15 = 10

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.

you write it like this (x,y) ----> (-x+4, y-5)

x2 - y2 = (x + y)(x - y) is an identity, not a function.

(x=y) (y=-x)

y/5

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).

I never learned a rule for reflection, but the easiest method would be to count the number of points the point of your figure/line from the x- axis or y-axis, and apply the same number onto the other side. That's how I always did it. It you were to just move the whole figure over, that would only be translation! make sure the figure/line makes sense of where it is.

(x,-y)

They are (-a, b).
