Please consider the following scenario:

The water level of a river is 34 feet, and it is receding at a rate of 0.5 foot per day.

Which formula best describes this scenario?

• y= 0.5x + 34

• y= -0.5x + 34

• y= -34x + 0.5

• y= 34x - 0.5

Betty worked at a golf course during the summer after eighth grade. After working for two weeks, she added her earnings to the gifts she got for graduation and found she had $570. After four more weeks of work, she had a total of $870.

Find her rate of change (slope) "m"

Find her initial gift amount (y intercept) "b"

Write and display your findings in
