<u>Answer:</u>
The line equation that passes through the given points is 7x – y = 13
<u>Explanation:</u>
Given:
Two points are A(2, 1) and B(3, 8).
To find:
The line equation that passes through the given two points.
Solution:
We know that, general equation of a line passing through two points (x1, y1), (x2, y2) in point slope form is given by

..........(1)
here, in our problem x1 = 3, y1 = 8, x2 = 2 and y2 = 1.
Now substitute the values in (1)


y – 8 = 7(x – 3)
y – 8 = 7x – 21
7x – y = 21 – 8
7x – y = 13
Hence, the line equation that passes through the given points is 7x – y = 13
After consideration I'm not sure but I think x=3 and y=6 I'm not a math whiz but this made sense to me.
Answer:
Step-by-step explanation:
First, find the percentage of the price after the sale occures
percent = 100% - 20%
percent = 80%
We need to find the price for the pairs with the percentage above
new price = percentage of new price/percentage of old price × old price
new price = 80%/100% × 55
new price = 4/5 × 55
new price = 44
The new price is $44
Now we estimate how much the tax
tax = 6% × 44
tax = 6/100 × 44
tax = 2.64
Calculate how much Josie will pay
pay = new price + tax
pay = 44 + 2.64
pay = 46.64
Josie will pay $46.64
