    I did that but then only two of them were on an exact point I need to know how to find the other two

    ya I got that part but as you can see only two of the vertices are on specific points how do I find the exact points of the other two

    are both the x and the 1 divided by 3 or just the x

    if just the x then x=4 but what about the y

    \[\large equation \space 1. \space -x+3\ge y\] \[\large equation \space 2. \space y \le \frac{1}{3}x+1\] \[\large y=y \rightarrow -x+3 = \frac{1}{3}x+1\]

    im confused i thought i was supposed to like combine them or something i still dont understand how to get the coordinates

    If the lines intersect, then they have the same (x,y) coordinates, so you can set the equations equal to each other and solve for x and y.

    how do i solve for y when its not in the equations when they are set equal to eachother

    Find x first, then use either equation to get y.

    so the coordinate is (4,-1)????when looking at the graph that doesn't make sense

    3-x=1+x/3 9-x=1+x 9=1+2x 8=2x x=4

    If you're going to multiply by 3 to clear your fractions, you have to multiply everything by 3. 3-x=1+x/3 9-3x=3+x 9-3=x +3x 6=4x x=3/2
