ok one moment
teller
  • teller
The help video they just gave me doesn't even tell us how to even do that kind problem it's everything else but those kind of problems
teller
  • teller
I know it's going to be 1 but I can't just put 1
jim_thompson5910
  • jim_thompson5910
are you familiar with finding the slope?
teller
  • teller
Not asking for the slope though and no.
jim_thompson5910
  • jim_thompson5910
well with finding any linear function, you find the slope first
jim_thompson5910
  • jim_thompson5910
all linear equations are in the form y = mx+b m = slope b = y intercept
teller
  • teller
See the video didn't say that...
jim_thompson5910
  • jim_thompson5910
what is the video saying (summarize it the best you can)
teller
  • teller
It was in the help section when I clicked it and it's input output tables and she just shows you how to find the missing numbers nothing about what in my work this is the video https://www.youtube.com/watch?v=y_aaOS6Q2qo
jim_thompson5910
  • jim_thompson5910
ok let me watch it
teller
  • teller
Frustrates me that they play students like this .They link a video and it's nothing on the problems about how to find N or anything like that ...
jim_thompson5910
  • jim_thompson5910
A big vague how she says "the rule is 3" at 41 seconds
teller
  • teller
Yea but when I do what she does it tells me I'm wrong on almost every single one I have to use those signs that you see on the right hand side of the picture.
jim_thompson5910
  • jim_thompson5910
ok so the video doesn't help with finding the nth term
teller
  • teller
That's what I said lol
jim_thompson5910
  • jim_thompson5910
yeah I'm just confirming. Anyways, as the inputs increase by 1, what's going on with the outputs?
teller
  • teller
its decreasing
jim_thompson5910
  • jim_thompson5910
by how much?
teller
  • teller
By 1 so the answer is going to be 1
teller
  • teller
I want to put 1-n-1 but I can't or 1xn-1
jim_thompson5910
  • jim_thompson5910
the x values (the inputs) are increasing by 1 the y values (the outputs) are decreasing by 1 (so we say -1) the slope is equal to the change in y over the change in x \[\Large \text{Slope} = \frac{\text{change in y}}{\text{change in x}}\] \[\Large \text{Slope} = \frac{-1}{1}\] \[\Large \text{Slope} = -1\] make sense?
teller
  • teller
so it would be -1 over 1?
jim_thompson5910
  • jim_thompson5910
yes which reduces to -1
teller
  • teller
so the final answer is -1 over 1 - 1? or just -1 over 1
jim_thompson5910
  • jim_thompson5910
-1 is just part of the answer
jim_thompson5910
  • jim_thompson5910
m = -1 is our slope. It tells us how things are changing
jim_thompson5910
  • jim_thompson5910
pick any pair of input and output values say x = 1 and y = 5 we will plug m = -1, x = 1 and y = 5 into y = mx+b and solve for b
jim_thompson5910
  • jim_thompson5910
y = mx+b y = -1*x+b ... replace m with -1 y = -1*1+b ... replace x with 1 5 = -1*1+b ... replace y with 5 now solve for b
teller
  • teller
6?
jim_thompson5910
  • jim_thompson5910
yep
jim_thompson5910
  • jim_thompson5910
m = -1 and b = 6 so y = mx+b turns into y = -1*x + 6 which is simplified to y = -x+6
jim_thompson5910
  • jim_thompson5910
now if you replace the x with n (changing variables is perfectly valid) we go from `-x+6` to `-n+6`
teller
  • teller
so the final answer is -n+6?
jim_thompson5910
  • jim_thompson5910
so the nth term is `-n+6` example: replace n with 4 and you'll get `-n+6=-4+6 = 2` which is exactly the output for the input of 4
jim_thompson5910
  • jim_thompson5910
correct
