What rule describes a transformation across the X-Axis?
(x,y) --> (x,-y)
Which rule describes a transformation across the x-axis?
Should be (x,y) -> (-x,y) Apologies if it's wrong!
What transformation is (x y)(y x)?
It is reflection in the line y = x.
The transformation f x y y x is what degree rotation?
90 degree anticlockwise.
What does the transformation y equals -x mean?
Assuming you're talking about transforming graphs, you mirror the graph along the line y = -x.

Which rule describes a transformation across the x-axis?
Should be (x,y) -> (-x,y) Apologies if it's wrong!
What rule describes a transformation across the Y-Axis?
Since the x coordinate will change, but not the y coordinate, take (x,y) and reflect across the y axis and you have (-x,y)
What transformation is (x y)(y x)?
It is reflection in the line y = x.
What is x divided by y represented as?
x over y
How is a point in a coordinate grid represented?
It is represented in the form of (x, y) whereas x and y have given values
What is the rule for the transformation formed by a translation 8 units to the left and 9 units up?
(x1, y1) = (x - 8, y + 9)
The transformation f x y y x is what degree rotation?
90 degree anticlockwise.
What is the rule if x is 9 and y is negative 3?
There is no specific rule. y = -sqrt(x) y = x - 12 y = -x/3 y = x2 - 84 are all possible.
What kind of transformation would add 4 to the x-values of every point in a shape and subtract 2 from the y values of every point in a shape?
The transformation from y = f(x) to y = f(x - 4) - 2
Does a transformation ever change the shape of a figure?
Yes. The transformation from y = f(x) to y=f(2x) will compress the shape along the x-axis by a factor of 2.
What is the rule for y equals and x?
y=m(x)+b
