The answer is in the picture
Your 71,1482 doesn't make sense. But regardless,
let x = the other car's cost.
You know the total spent and the cost of one car. So logically, if you subtract the two you'd get the price of the second car.
You can do $38,295 + c = $71,1482.
Or $71,1482 - $38,295 = c.
(-4,4) (2,1)
gradient = (1-4)/(2--4) = -1/2
y = mx + c
y = -1/2x + c
Replace point (2,1) in the equation
1=-1/2(2) +c
c = 2
Equation : y = -1/2x + 2
y-2 = -1/2x
Answer is C.
Hope it helped!
