A) $y = - 170 x + 4928$
B) $y = - 170 x + 3228$
C) $y = \frac { 1 } { 170 } x + 3228$
D) $y = 170 x + 3228$

The investment grows from $3228 in 1994 (x=0) to $4078 in 1999 (x=5). The increase is $850 over 5 years, so the annual growth rate is $850 / 5 = $170 per year. Thus, the equation is $y = 170x + 3228$, where $x$ is the number of years since 1994.
