Question 268737: solve each system of inequalities by graphing
18.
y > 4
y < |x-1|
21.
yless than or equal to -4/3x
ygreater than or equal to -|x|
please help me with these two questions. I have no idea how to find solutions for systems of inequalities with absolute value brackets... Thanks so much!!! ANY help is very much appretiated!

solve each system of inequalities by graphing
18.
y > 4
Graph y = 4 as a dashed line.
Shade the half-plane ABOVE the dashed line.

-----------------------------------------------
y < |x-1|
Graph y = |x-1| as a dashed line.
Shade the area below the v-shaped graph

21.
yless than or equal to -4/3x
Graph y = (-4/3)x as a solid line.
Shade the half-plane BELOW the line.

--------------------------------------------------------------
ygreater than or equal to -|x|
Graph y = -|x| as an upside-down V.
Shade the area ABOVE the V.
