    Please help graph inequalities

    Find 3 (X,Y) pairs that satisfy the system of inequalities and three (x,y) pairs that do not. Then, draw a graph showing all the soluions.

    1. 4x+6y <= 24 and x+5y<=10

    2. 2x-y<= -1 and -x+y> -1

    alright, so you have

    (24 -4x)/6 is less than or equal to (l.t.e) y
    and (10 - x)/5 l.t.e y

    graph the two of those. and anything that is under both of the lines will satisfy both of them.
    Anything that is over one or both of the lines won't.

    THe second one is y>1+2x and y>-1-x
    graph those and look for something that is greater than both of them that will satisfy both restrictions.

    If you're having issues graphing them. Then just graph each of them as if it was = y rather than < or > or w/e. THen shade above the line (for greater than y) or below the line (for less than y)
