Could someone explain how you graph a function? Giving an example would help me a lot, thank you.

with the pencil :P welcome to open study ! first why the cat in the profile pic isn't smiling , TheSmilingCat?? and linear function ??

  • anonymous
lol, thanks for replying, but it isn't smiling because smiling is too mainstream ^_^. Also, yes i am working on linear function
Nnesha
  • Nnesha
aww :( alright y =mx+b linear equation where m is slope (rise /run) and b is y-intercept lets say we have y = 3x +4 where 3 is slope and b is y-intercept

Looking for something else?

to graph linear function we should start with the y-intercept y-intercept is a point where line intersect y-axis |dw:1442182449985:dw|

I remember going over this in class, i completely forgot about the rise over run, thank you so much

\[\huge\rm y=\color{ReD}{3}x+\color{blue}{4} ~~~~y=\color{Red}{m}x+\color{blue}{b}\] m= slope b= y-intercept

so start with y-intercept which is 4 in this equation so draw a point at 4 |dw:1442182609050:dw|

now slope is =3 3 is same as 3/1 \[\huge\rm \frac{ 3 }{ 1 } =\frac{ rise }{ run }\] so i go up 3 unit and then right one |dw:1442182704073:dw| then just draw a line

Okay, i took notes this time, just in case i forget again, thank you so much!

my pleasure feel free to ask question if you didn't get it! btw hint if slope is negative then line should decrease (start from 3nd quadrant to 4th) if slope is positive then line should increase (Start from 3rd quadrant to 1st ) :=)
