The equation is an illustration of a linear function
The rate of change is 10 and the initial value is 25
<h3>How to determine the rate of change and the initial value</h3>The equation is given as:
A linear equation is represented as:
Where:
By comparison:
b = 25
m = 10
Hence, the rate of change is 10 and the initial value is 25

<u>Answer:</u>
The median amount of water is higher when the eighth day's amount is included in the data.
<u>Explanation:</u>
Given the ounces of water drank is 60, 58, 64, 64, 68, 50, 57
Arranging in ascending order: 50, 57, 58, 60, 64, 64, 68
Calculating the median of the above data
Median (when n is odd) =
where n =7
Median = 4th term = 60
When the eight day is added,
Series will be: 50, 57, 58, 60, 64, 64, 68, 82
Median (when n is even) =
Median =
So, here we can say that median has increased after adding 82 in the data
