Thread: graphing integers and rationals

how would I Graph the solution set for each as follows one example? -7<x<-2,xEI

If -7< x <-2 only:

That means x is "between" -7 and -2, but -7 and -2 are not parts of the x-values, so,
draw a horizontal number line,
put holes or small circles at -7 and -2,
define or mark with heavy line the distance between the two holes.

That is the graph of -7 < x < -2.

----------------
If -7 < x < -2, xEI

Since I don't understand what you mean by xEI, I don't know how to graph that.

Ummm, by xEI you mean x belongs to the set of integers only?

Okay then.

Draw a horizontal number line.
Draw holes on -7 and -2.
Draw big dots, not holes, on -6,-5,-4,and -3.

That is it.
