    It's not clear what you asking for. Please state the full problem. Are you asking for 4 points in the region? Are you asking for 4 points on the graph of the line? Does X and Y have to be integer valued?

    It's a simple line, (I think)

    Hi,

    The equation is the area above a line.
    y>=x+3 consists of all the points including and above y=x+3 which is a line with gradient 1, x intercept (-3,0) and y intercept (0,3)

    Yes it is a region bounded by a simple line. I can name lots of points that have something to do with the line and the region. It is not clear what the question is asking.

    I think the term "gradient" is too advanced for pre-calculus, although it's certainly correct and might be understood. Slope seems to be more commonly because early algebra only teaches about lines with constant gradients. I'm not correcting you, I just want to point out to take in mind the level of the poster.

    Agreed. Badly written question. "on a graph" could mean so many things.
