If you want 20 points answer these questions and make it brain list 1.)What is the mapping notation for translating point (x, y) down 3 units?
a.)(x, y−3)
b.)(x−3,y)
c.)(x, y+3)
d.)(x+3,y)
2.)What translation vector translates A(−2,7) to A′(5,−1)?
a.)(7,−8)
b.)(−7,8)
c.)(3,6)
d.)(3,−6)
3.)Which transformation maps B(2,5) to B′(−2,−5)?
a.)A 270° rotation
b.)A 180° rotation
c.)A 90° rotation
d.)Reflection about the y-axis
4.)Point (a, b) is reflected about the x-axis. The resulting point is then reflected about the y-axis to produce a final point. Which transformation maps the original point directly to the final point?
a.)A translation down b units and to the left a units
b)A 90° rotation
c.)A 180° rotation
d.)A 270° rotation
