Find the coordinates of the image of a segment whose endpoints are:
D(-2,3) and K(1,2) after each transformation.
----------------
Looking at D(2,-3)
A translation of right 4 and down 2?
You go to (2+4,-3-2) or (6,-5)
--------------------------
A reflection over the x-axis?
You go to (2,3)
----------------------------
A rotation of 90 degrees about the origin?
That depends of which way you rotate.
If +90 degrees (counter clockwise), go to (3,2)
If -90 degrees (clockwise), go to (-2,-3)
============
You can work it out for K(1,2). Draw the coordinat
system. Notice the x and y distances from the axes.
Perform the translation and you will see what the
new coordinates have to be>
