  1. The table below shows the various values for x and y.

x / -3 / -1 / 2 / 4 / 5
y / 5 / 3 / 0 / -2 / -3

Which equation best describes the relationship between x and y?

  1. y = -x + 5

  1. Lenny is a member of a local gym. He pays a one-time fee of $120 to join the gym, then has monthly dues, m, of $15.25. Which equation could be used to find c, Lenny’s yearly cost for being a member of the local gym?
  1. c = (120 + 15.25)m
  2. c = 120 + 15.25m
  3. 120m + 15.25
  4. (120 + m)(15.25)

(4x + 2) = (10x + 1)

  1. x = 3
  2. x =
  3. x =

Which rule describes the dilation?

  1. ( x, y ) ( x , y )
  2. ( x, y ) ( x , y )
  3. ( x, y ) (x , 2 y )
  4. ( x, y ) (x , 3 y )
