Relation
Linear
Exponential
Function
Is the relation a function?

Derek works at Subway making $9.25 an hour. The function d(x) = 9.25x tells us how much money Derek makes after x hours of working. What is the meaning of d(4) = 37?
After 4 hours of work, Derek makes $37.
Derek needs $4 more to have $37 total.
After working for 4 days, Derek makes $37 total.
After 4 hours of work, Derek now makes $37 an hour instead of $9.25.

What linear relationship defines the movement of a translation?
Points are translated the same distance along (a) (parallel or perpendicular) lines.
Fill in the blank.
Write a rule for the translation.
(x - 1, y + 2)
(x - 2, y + 1)
(x + 2, y - 1)
(x + 1, y - 2)
Identify the transformation from ABC to A'B'C'.
(x + 8, y + 4)
(x - 8, y - 4)
(x + 4, y + 8)
(x - 4, y - 8)

What transformation is happening?
(x, y) ----> (x + 2, y - 3)
translations up 2, left 3
translations right 2, up 3
translations right 2, down 3
translations left 3, right 2
