    for finding the x and y intercepts just cover the other variable .. for example x+y= 7 cover the x and you get y=7 cover the y and you get x= 7

    we do have textbooks but my teacher doesn't let us use it. we only have what frayed diagrams she gives us and our workbook with just problems in it. ): the textbook would be reeeeally useful.

    ok the next 2 is hard to explain, but I remember it as "y ski" aka why ski.. if it is only y then it is horizontal, so why would you ski on no slope..
