    set x = any number you want and find out what y is for that value of x. set x = any other number and find out what y is for that value of x. now you have two sets of x and ys. those represent two points (x1 y1) and (x2 y2) draw a line through those two points. that line is the graph of your equation

    put x=0 in the equation find out y. then put y=0 and find out x. plot the two (x,y) values in the graph and draw a straight line joining thesr two points..

    @adi: dont you think taking any of the variables as zero would simplify things better?

    @deep yes, but that is not the point of how to plot a graph and what it means to plot a graph.

    okay so you chose 3. set x =3 in your equation x+2y = 6

    the point to graphing is just finding two points on the graph of a linear equation and joining them. i dont know what "point" you are referring to. no offense buddy

    the point of graphing is to find a visual representation of an equation. it doesn't matter which points you choose.

    right, so your two points are (3,1.5) and (2,2) so now, on a piece of graph paper, draw a line through those two points. that is your answer.

    good, note that you could have chosen any number for x and you would have got a corresponding value for y.
