    slope of line

    given the slope of the line and a point of the line, find three additional points that are on the same line

    A.) (2,1) and m equals 0

    B.) (2,1) and m is undefined


    Find the slope and the y-intercept of the equation of the line algebraically
    A.) 5x-2 equals 0

    Hello,

    If the slope is 0, then the line is horizontal, that is to say : any point on this line has a fixed ordinate (here, it's 1)

    B.) (2,1) and m is undefined
    This only holds true when the line is vertical, that is to say : any point on this line has a fixed abscissa

    Find the slope and the y-intercept of the equation of the line algebraically
    A.) 5x-2 equals 0
    This can be written x=2/5
    Refer to question B.)
