Does a trend line always pass through every point on a scatter plot?

No, it does not and it's not supposed to. A trend line is drawn to go through in the best way possible, to go through the "center" of the points as best as it can. It may hit some of the points, but not all of them. Generally, the idea is to try to get the trend line to have as many points "above" it as it does "below" it to say you've gone through them evenly.

Answer:

Agree. All dots will not be connected. If the scattered dots are not on the best fit line, then it will not be connected

I found a place that will give me a 20 percent discount if i spend over 50 dollars. My bill is 75 dollars. How much money will i

const2013 [10]

X of 20% = y
x - y = 75

x = total amount
y = discounted amount

x * 20/100 = y
x * 0.2 = y
replace y with 0.2x in other equation

x - y = 75
1x - 0.2x = 75
0.80x = 75
x = 75/.8
x = 93.75

Check:
93.75 * 20/100 = 18.75
93.75 - 18.75 = 75
x = 93.75
y = 18.75

Answer: Total amount without discount is $93.75

//BTW not sure about this, but kind of make sense

X should equal 4.9
than fill in the equation for x
8(4.9-3.7)
you then subtract in the parenthasis
getting the answer of 1.2
finally multiply 1.2x8
Your final answer is 9.6
