Question

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

Answer 1

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

Answer 2

lol, thanks for replying, but it isn't smiling because smiling is too mainstream ^_^. Also, yes i am working on linear function

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

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

Answer 7

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

Answer 8

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
then just draw a line
