The linear function for the number of trimmers assembled is:
y = 7 + 4x.
--------------------------------
A linear function has the following format:
In which:
- a is the rate of change.
- b is the fixed amount.
--------------------------------
- In an earlier shift, 7 trimmers had already been produced, thus 7 is the fixed amount, that is,
.
- Diane assembles 4 trimmers per hour, thus the rate of change is 4, that is,
- The <u>amount of trimmers y produced after x hours</u> is given by:
