1. Do Now
Grab a whiteboard, marker, & sock from student station
If you are not in your seat, you are not tardy
Return to seat and answer the following question:
For pre-image coordinate (-7, 1), what would be the image coordinate after a reflection over the x-axis?
(-7,-1)

2. Give the new coordinates of the reflected image after a reflection over the y-axisz

z’(5,1)
y’(3,6)

3. If point A is (-19,7), give the ordered pair of A’ rotated 180 degrees.

14. Ben is wanting to build a model rail car that is 1 foot in length
Ben is wanting to build a model rail car that is 1 foot in length. The actual length of a rail car is 50 feet in length. What is the scale factor that Ben needs to use to make sure his model rail car is accurate?
k = 50 or dilate by 5000%
