I've been stuck on these for a while and I'm confused. Also, forgot if I am supposed to shade part of the graph or if it is just a line. Please help! Thanks.
+128407 I'll do the first one.....If you have trouble with the rest...let me know
First a " ≥ " or a " ≤ " means a solid line
While a " >" or a "< " means a dashed line
The easiest way to do this is to graph these lines
y = 2x - 1 and y = -3
So....look at the graph here : https://www.desmos.com/calculator/hk7nfsdyrr
The two lines split the grah into 4 quadrants
Picking a point in each quadrant I've selected (0, 0) (-2, - 4) (0, - 4) (2, 0)
Put each set of coordinates into the original inequalities
If you do this....you will note that the point (2,0) is the only point that makes both inequalities true....
So.....we shade like this : https://www.desmos.com/calculator/6fzq3zdgcz
