Y>=2x-4 It is not a dotted line so it is also equal to and it is y> because the origins (0,0) is shaded in. It is 2x for the slope because the line goes 2 up and 1 down.
The -4 will translate the graph of f(x) 4 units to the right. Then the -2 before the x will stretch it vertically with factor 2, then reflect it in the y -axis. Finally the + 5 will translate the graph 5 units vertically upwards
