The equation is
3x-4y-8=12
Which can be rewritten as
3x-4y =12 +8
3x-20 = 4y
y = (3/4)*x - 5
We need to check each individual case
(0,-5)
y = (3/4)*(0) - 5
y = -5
True
(4,-2)
y = (3/4)*(4) - 5
y = -2
True
(8,2)
y = (3/4)*(8) - 5
y = 1
False
(-16,-17)
y = (3/4)*(-16) - 5
y = -17
True
(-1,-8)
y = (3/4)*(-1) - 5
y = -23/4
False
(-40,-34)
y = (3/4)*(-40) - 5
y = -35
False
(0,-5) (4,-2) and (-16,-17) are the solutions

Answer:
The percent increase in the price of the car is <u>31.36%</u>.
Step-by-step explanation:
Given:
A car dealer buys a luxury car for $65,200 and sells it for $85,650.
Now, to find the percent increase in the price of the car.
Cost price of the luxury car = $65,200.
Sell price of the luxury car = $85,650.
So, the price of the car increased by:
Sell price of the luxury car - Cost price of the luxury car.
<em>Thus, the price of car increased by $20,450.</em>
Now,to get the percent increase in the price of the car:
Therefore, the percent increase in the price of the car is 31.36%.
