Question

The graph below is represented by which system of inequalities? (Graph in comment)

-x + 3y < 9
y > -2x + 1

-x + 3y 9
y > -2x + 1

-x + 3y < 9
y -2x + 1

None of these systems represent the graph shown.

Answer 1

Isolate your y's and draw both lines. You will see which one match. I suppose you know how the shading works.

Answer 2

I think you forgot some signs in your equations also.
