Answer:
Part 1) The rate of change is
Part 2) The initial value is
Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to
where
m is the slope or rate of change
b is the y-intercept or initial value
step 1
Find the slope or rate of change
The formula to calculate the slope between two points is equal to
we have the points
(5,12)and (2,6)
substitute the values in the formula
therefore
The rate of change is
step 2
Find the initial value
we have
substitute in the equation
solve for b
---> initial value
The linear equation is equal to
The y-intercept or initial value is 2
Answer: 0.57 hours each day or 34.28 minutes each day.
Step-by-step explanation:
1. You know that:
-Alejandra worked on the animal report for school for 4 hours in a week.
- A week has seven days.
2. Therefore, to calculate the number of hours she worked on the project each day (which you can call ), you can divide the number of hours worked on in a week by 7 days.
3. Therefore, you obtain the following result:
Multiply the result by 60 to obtain the time in minutes, then:
