    i think that it's 2) a broken line, shaded above the line

    a broken line would just be > a solid line is used to indicate inclusiveness, like ≥

    no that's just the y-intercept of the equation. you shade where the inequality suggests. in this case it's greater than, so everything ABOVE this equation (including this equation) is valid.

    so for y ≤ 7 − 2x it would be a broken line, shaded above the line right?

    no. it is less than, which means below. a broken line is for < and >, and solid line is for ≥ and ≤
