Okay, so for every other equation something is being raised to an expoenent, when something is being raised to an exponent this means that the line will be curved to a degree like this. |dw:1432948202275:dw|

Which statement best explains whether y = 4x + 8 is a linear function or a nonlinear function? It is a linear function because the graph contains the points (8, 0), (12, 1), (16, 2), which are on a straight line. It is a nonlinear function because the graph contains the points (8, 0), (12, 1), (16, 2), which are not on a straight line. It is a linear function because the graph contains the points (0, 8), (1, 12), (2, 16), which are on a straight line. It is a nonlinear function because the graph contains the points (0, 8), (1, 12), (2, 16)

One moment let me graph this.
MeowLover17
  • MeowLover17
first off do you know how to graph it??
anonymous
  • anonymous
kk
anonymous
  • anonymous
a little bit
MeowLover17
  • MeowLover17
Okay what is the slope in this case? and what is the y-intercept?
MeowLover17
  • MeowLover17
remember y=mx+b m being the slope and b, being the y-intercept.
MeowLover17
  • MeowLover17
No, here ill graph it so you can better understand it, the y-intercept is the b
anonymous
  • anonymous
i know it your y-intercept is 8
MeowLover17
  • MeowLover17
https://www.desmos.com/calculator
MeowLover17
  • MeowLover17
yes your y-intercept is 8
anonymous
  • anonymous
i don't see anything on the website
anonymous
  • anonymous
how do you even use this graphing calculator
MeowLover17
  • MeowLover17
plug in your equation.
anonymous
  • anonymous
the whole thing
MeowLover17
  • MeowLover17
remember slope is rise over run, so you would start at positive 8 to graph this then go down 4 left 1 or up 4 right 1
MeowLover17
  • MeowLover17
Yes
anonymous
  • anonymous
now what do i do after i have plugged in the equation
MeowLover17
  • MeowLover17
Okay i have your answer, but i wont give it to you yet.
MeowLover17
  • MeowLover17
So, tell me does your graph have any repeating x coordinates??
anonymous
  • anonymous
no
MeowLover17
  • MeowLover17
no, is correct and what does this mean?
MeowLover17
  • MeowLover17
is it a function or nonfunction?
anonymous
  • anonymous
that it is a linear function
MeowLover17
  • MeowLover17
Correct. now between your first choice and third choice which one do you think is corect? based of the information it tells you
MeowLover17
  • MeowLover17
Your third choice would be correct.
MeowLover17
  • MeowLover17
anything else?
anonymous
  • anonymous
it is number three
MeowLover17
  • MeowLover17
Yep your right,
anonymous
  • anonymous
let me check if there is anything else that i need help with k
MeowLover17
  • MeowLover17
Alright ill be here
