Which system of inequalities is represented by the graph?
melisa1 [442]

Answer:

Option 3 is the correct answer.

Step-by-step explanation:

In this graph the red area is above the line y = -1 which represents y ≥ (-1)

Another graph is of a line y = mx + c which passes through (2, -1) and (0, 0)

where m = (y-y')/(x-x') = (1+0)/(0-2) = -1/2

and y intercept c = 0

Therefore line is y = -1/2x

and the blue area will be y ≤ -1/2x below the line.

Hence Option 3 is the answer.
