The average water level in a retention pond is 6.8 ft. during a drought the water level decreases at a rate of 3 in/ day. a. write a leaner function w that represents the water level w(t) (in feet) t days after the drought begins.

Step-by-step explanation:

1. The form of a linear function is:

Where m is the slope and b is the y-intercept.

2. You know that the water level decreases at a rate of 3 in/day, this means that the slope of the function is -3.

3. The average water level in a retention pond is 6.8 feet, this means that the maximum level of the water is 6.8 feet, because the function decreases while  x increases.

4. Then, the linear function is:

51-50

step-by-step explanation:

answer: x=3 and y=4
