Which graph is a sloution set to the open sentence? 12 < 3b or 2b + 14 < 4

Maggie, you must either share the graphs or forget about them and solve the entire problem yourself with your own graph.

12 < 3b reduces to 4<b, and 2b + 14<4 reduces to 2b < -10, or b < -5.

You have only one variable here (b), so your graph will be one-dimensional (a horizontal line which is the b-axis).

First place a circle (open circle) at b = -5, and then draw an arrow to the left from b = -5.  Next, place a circle at b = 4, and then draw an arrow to the right from b = 4.  Note that there will be no arrow between b=-5 and b=4.

Two because two of one thing is two.
