    y = a constant

    a horizontal line that passes through all points with y-value equal to that constant

    x = a constant

    a vertical line that passes through all points with x-value equal to that constant

    what do you mean "y is no number?"

    y + 6 = 3

    y = -3

    step 1: go down 3 units on the y-axis ... put a dot there.

    step 2: draw a horizontal line that passes through the dot.


    simple enough?

    i do not understand where you have difficulty.

    skeeter told you exactly what you need to know.

    lets use an example, i suppose



    example 1: say we want to graph y = 1

    this is just a horizontal line that cuts the y-axis at 1



    example 2: say we want to graph x = 1

    this is just a vertical line that cuts the x-axis at 1
