    all the answers are in y = mx+b form, b is where they cross the y-axis. what is the y-intercept of the dotted line?

    yes, the line is shaded below and dotted, so it is 'less than', y < m*x + 3

    just need the slope m, for each increase in 1 x unit, y decreases by 1, so slope is -1

    none of the answers have -1 in them. Is it D?

    oh, -1*x is the same as -x

    Are those in groups of 2, or can you chose any 2 equations...both are in there

    A: y > 2x − 3 y > −x − 3 B:y < 2x − 2 y < −x + 3 C: y ≤ 2x − 2 y > −x + 3 D: None of the above

    the other line has a y intercept of -2 and a slope of 2, and is shaded under and solid \[y \le 2x -2\]

    Solid line means the answers can include the points on the line, so it can also be equals

    hmm, actually it is hard to tell what side the dotted line is shaded on... is the green area the overlapping region, or the yellow

    probably the green, so yeah C

    Both, the colors are simply shading in the space between the two lines.

    one of the areas is shaded by both lines

    i would say C, the dotted line is shaded above , so it is y >

    green is darker, so probably the overlaping region

    The rason I chose C was because it is the only answer with: y≤2x−2

    yeah say C, the graph is just wrong, they are missing some of the single shaded area

    one of the white triangles should be single shaded by the dotted line
