Answer:
Step-by-step explanation:
The line has two clear points (6,10) and (2,2)
y=mx+b
m=(y2-y1)/(x2-x1)
m=(2-10)/(2-6)=-8/-4=2 so far our line is
y=2x+b, using point (2,2) we can solve for b
2=2(2)+b
2=4+b
b=-2 so our line is
y=2x-2, and we want to know the coordinates for (4,b)
b=2(4)-2
b=8-2
b=6
Now we want to know the coordinates for (a,8)
8=2a-2
10=2a
a=5
Add 8 on both sides of the equation.
x = -12
There’s your answer!

I think the answer would be 12
X= purchase price
Multiply purchase price by sales tax % to equal the amount of sales tax.
(8.75% * x)= $15.75
convert % to decimal (8.75% ÷ 100)
0.0875x= 15.75
divide both sides by 0.0875
x= $180.00 purchase price
ANSWER: The purchase price is $180.00 (to nearest cent).
Hope this helps! :)
