    see attachment..

    btw, this is really basic stuff
    you just pick an x and calculate the y. you need to pick at least 2 different x's to calculate 2 different y's and get 2 different points (x,y) through which you can draw a line.

    for y = 3x + 4

    lets say x = 0
    y = 3 * 0 + 4 = 4
    T1 (0,4)

    then lets say x = -1
    y = 3 * (-1) + 4 = -3 + 4 = 1
    T2 (-1,1)
    and you just draw a line through these 2 points..
