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

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

    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

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

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

    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 ) :=)
