If you have a set of points ( or numbers starting off, like (1,1) and (2,2) or what so ever. you have a slope. As long as you numbers continue to grow, remain constant, or decrease, you have Linear Data
Linear is a smart word for "Straight.
Think of it like this. Your parents give a dollar a day.
Day one you have one dollar
day two you have two dollars.
So if you can figure the slope of the line. you can figure how much you will have in a month!.
This is just an arithmetic sequence because each term is a constant difference from the preceding term, called the common difference.
Any arithmetic sequence can be expressed as:
a(n)=a+d(n-1) where a=initial term, d=common difference, n=term number
In this case a=-8 and d=3 so
a(n)=-8+3(n-1) which you can simplify if you'd like
a(n)=-8+3n-3
a(n)=3n-11
Ok so the queistonn is
______ can be either addition subtraction division or multiplication
the answer is <u>an operation symbol</u> since it operates or does things. it's like a verb
The answer to the question is 2
The answer is B. $1600 because you have to subtract it
