Which one is it? 1,2,3 or 4?
Kobotan [32]

Answer:

3

Step-by-step explanation:

If you look on the graph, you can see that the y intercept is at -4. This easily takes out answers 1 and 2 because they have a y intercept a +3. Next you notice that any point with a y value must be equal to or less than 4/3x-4. Since every point below the line has a y value less than any point on the line, it must mean that y< or =4/3x-4
