b) 3x is greater than or equal to 1
c) x - 3 is greater than or equal to 1

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

i think da answer is
