%of goal reached
<80
80
100
120
Incentive
n/a
\(4,000with an additional \)125added per percentage point from 81-99%
\(6,500with an additional \)125added per percentage point from 101-119%
\(9,500with an additional \)125added per percentage point from 121%

If a loan officer makes 95%of his or her goal, write the linear function that applies based on the incentive plan table. In context, explain the

y-intercept and slope.
