    Intercept is where a line crosses the axis. So, where would you cross the y axis and where would you cross the x axis?

    @anaaxcx click the pencil on my drawing then plot where you think 9 is on the xy axis

    sorry, if the y intercept is 9, where would that be on the xy axis?

    That point is (3,9). The coordinate for an intercept on the y axis is (0, #) and for the x axis is (#, 0).

    the y axis is the vertical axis so the y intercept must go on this vertical axis somewhere

    Right yeah I get the part that you have to put it on its vertical axis

    so you agree that it would be like this, right? |dw:1442287636074:dw|

    that point is one tick below the 10, so on the "9" of the y axis number line

    That point is the ordered pair (0,9) |dw:1442287784132:dw|

    Okay, so that is the y intercept 9. Now where will the x intercept be?

    That is the y axis. The x axis is the horizontal one. Try again.

    Very good. Now, connect the dots and you will have your line who's y intercept is 9 and who's x intercept is 3.
