The equation of the line is y =
x + 9
Step-by-step explanation:
The equation of a line in slope-intercept form is y = m x + b, where
- m is the slope of the line
- b is the y-intercept ⇒ the value of y when x = 0
∵ The line has a slope 
∴ m = 
∵ The y-intercept is 9
∴ b = 9
- Substitute the values of m and b in the form of the equation below
∵ y = m x + b
∴ y =
x + 9
The equation of the line is y =
x + 9

Part A:
The differential equation is:
y '= 0.08y
The initial condition is:
P (0) = 500 Part B:
The formula for this case is:
P (t) = 500exp (0.08 * t) Part C:
After five days we have to evaluate t = 5 in the equation.
We have then:
P (5) = 500 * exp (0.08 * 5)
P (5) = 745.9123488
Rounding:
P (5) = 746
