Step-by-step explanation:
Since we have given that

By using logarithmic on both sides we get,

(∵
)
Now, differentiating on both sides ,we get,



Answer:
The equation of the line would be y = 1/8x - 3
Step-by-step explanation:
to find the slope intercept form of the line, you must first find the slope. You can do this using the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (-2 - -4)/(8 - -8)
m = 2/16
m = 1/8
Then you can use this slope along with either point in point-slope form. Then solve for y.
y - y1 = m(x - x1)
y + 4 = 1/8(x + 8)
y + 4 = 1/8x + 1
y = 1/8x - 3

The question seems not to be complete, below is a possible complete question:
Kristin earns $6.50 for every hour she babysits for the Overstreet family. Part A: Last Friday, Kristin babysat for 4.5 hours. How much money did she make during that job? $__________ Part B: Mrs. Overstreet has told Kristin that she will pay her $45.50 for tomorrow's babysitting job. How many hours will Kristin babysit then? __________ hours
Answers:
Part A: She makes $29.25
Part B: She babysat for 7 hours
Step-by-step explanation:
Part A:
amount earned per hour = $6.50
Number of hours worked = 4.5 hours
1 hour = $6.50
∴ 4.5 hours = 6.50 × 4.5 = $29.25
part B:
total amount to be earned = $45.50
earning rate = $6.50 per hour
