Question

Prompt

The length,

y

, of a beluga whale was

160 centimeters (cm)

when it was born and increased an average of

4.7 cm

per month for the first

12

months after it was born. Which equation best represents this situation, where

x

is the number of months after the whale was born?

y = 4.7 x + 160

y = 160 x

y = 4.7 x + 4.7

y = 160 x + 160
