Answer:
Step-by-step explanation:
First you have to find the slope
M= y2-y1/ x2-x1.
6-4 / 8-7 = 2/1 or 2
Then you pick one set of coordinates and plug the information into the formula. It doesn't matter which set you use as long as you plug the information in correctly.
I will choose (6,4)
Slope intercept formula is y-y1 =m(x-x1)
Y-4=2(x-6)
Then you simplify.
Y-4=2x-12
+4. +4
Y=2x-8 is your solution.

Answer:
<u>110.000</u>
<u></u>
Step-by-step explanation:
Selling at a loss of 5% means it was sold for 95% of its purchase value.
If 120.175 equals to 95% then 100%(the purchase value) is 126.500.
120.175/95*100 = 126.500 (plenty of other ways to calculate this, but this is one of the easiest)
So now we change to the dealer's perspective, he sold the car for 126.500 and for him that meant a 15% profit. If the purchase value is 100%, then the sale value is 115% (purchase value+15% profit)
Calculate the purchase value:
126.500/115*100 = 110.000
The dealer bought the car for 110.000, sold it for 126.500, so he made a profit of 16.500 (126.500-110.000) which is a 15% profit (15% of 110.000 is 16.500).
