nobody can answer these questions unless you give the full problem.

@Kaylaaa what are the signs between the sides of the inequality?

anonymous · Answer

Sorry my bad , its y <  x - 5
y > -x - 4

anonymous · Answer

Okay. IMO, I would just graph this.
y < x-5 -> y-int at (0,-5), slope of 1|dw:1340643275651:dw|
Test a point. (0,0)

0< 0-5
0<-5
No, so (0,0) isn't in the graph.
So...

anonymous · Answer

they are in slope intercept form. SO either plot it by hand or use google. and ttreat the inequalities as = https://www.google.com/search?rlz=1C1CHFX_enUS470US470&sugexp=chrome,mod=2&sourceid=chrome&ie=UTF-8&q=x-5%2C+-x-4

Next, you want to graph the other inequality. 
y > -x - 4 -> y-int at (0, -4) and a slope of -1.
