Parallel lines has equal slopes. Hence slope of line = -1/2
equation of line is (y - y1) = -1/2(x - x1)
y - (-6) = -1/2(x - 4)
y + 6 = -1/2x + 2
y = -1/2x + 2 - 6
y = -1/2x - 4
Answer:
y = x + 1/2

Answer:
Cost before sales tax= 16 dollars
Total cost= 17.16 dollars
Step-by-step explanation:
We know the sales tax rate is 7.25 percent.
To find the cost from the tax rate, we divide the cost of the sales tax by the rate.
1.16/0.0725 = 16 dollars
Now to find the total cost, add the cost before the tax rate by the sales tax amount.
16+1.16= 17.16 dollars
