1 brainliest plz and thank you
just a quick clarification, tis usually -4.9 and that's a rounded number to reflect earth's gravity on an object in motion, but -5 is close enough :)

Line is Passing through the Points (-3 , -1) and (-5 , 4)
Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :
here x₁ = -3 and x₂ = -5 and y₁ = -1 and y₂ = 4
Answer:
Adam's car will be 8,406£ in 22 years.
Step-by-step explanation:
I. Find the lose value of 2.5% car by
2.5/100 = x/18,680
46,700/100 = x
x = 467 or the lose value in 1st year.
II. Find the true value of Adam's car by
n year = 18,680 - 467(n)
1st = 18,680 - 467(1)
= 18,213 means if he sell his car now, he'll get 18,213£
22th = 18,680 - 467(22)
= 18,680 - 10,274
= 8,406£
That makes 8,406£ is the right answer.
Hope that help :)
