PLZ HELP ASAP

Answer 1

$5 > 4 \\ - 2 \leqslant 2(5) - 5 \\ - 2 \leqslant 5$
B is true for both inequalities.

Answer 2

Plot the line x = 4 with a dotted line and shade in the area below the line because x is greater than. If you are in America then shade the other way round btw! Then plot the line y =2x-5 with a solid line and shade in the area above the line. Again America is the other way round. Look at where you haven’t shaded (America again is where you have!) and write down the coordinates that fit with where you haven’t shaded. I haven’t done the graph so I can’t tell you but do the graph and do this.

Another thing is that if the line is solid, you can count coordinates on it, but if it is dotted then you can’t.

If you want me to explain how to draw the lines out then just comment and I will draw it out for you.
