Question

100 Points

If the polygon is translated 3 units down and 4 units left, what will the coordinates of the new image be? Use prime notation in expressing the new coordinates.

Answer 1

point A is at (1,5)

shift it 2 units down to get to (1,3). notice how I subtracted 2 from the y coordinate

then shift it 4 units left to get to (5,3). I added 4 to the x coordinate. This is the location of A' (read as "A prime")

-------------------------------------------------------

So A is at (1,5) while A' is at (5,3)

take each coordinate

subtract 4 from the first number and 2 from the second number

for example one coordinate is (1,5) subtract 4 from the first number, 2 from the second, get (−3,3)
