Answer: <span>rotation and dilation.
While rotation only rotates (obviously) the figure, dilation preserves the shape of the figure (that is, preserves the angles) but changes the distances: it makes the figure smaller.
</span>
The other 2 sequences of transformations only change the position of the figure, but the angles and distances remain intact.
X=(y-b)/m........ . . . .
First distribute
combine like terms
subtract 6x from both sides
then you get no solutions which is a special case
3x^2 - 72 = 0
3x^2 = 72
x^2 = 24
x = squareroot(24)
x = 4.9
