    parametric equation of line

    A line L: 2x -3y = 1 is given.
    Show that the coordinates (x,y) of any point on the line L can be written as

    x = 2 + 3k and y = 1 + 3k


    I don't know how to show it.
    Is that just by putting x = 2 + 3k and y = 1 + 3k into the equation of L?

    Hello, ling_c_0202!

    There must be a typo . . .


    A line L\!:\;2x -3y \,= \,1 is given.

    Show that the coordinates (x,y) of any point on the line L can be written as
    . . x \:= \:2 + 3k and y \:= \:1 + 2 k

    I don't know how to show it.
    Is that just by putting x = 2 + 3k and y = 1 + 2k into the equation of L?

    Yes!
