Inequalities
x - 4y =< 4 ------ (1)
y < x + 1 ----- (2)
Express the inequalites as equations
x - 4y = 4 -4y = -x + 4
y = -x/-4 + 4/-4
y = x/4 - 4
y = x + 1
Turn the equation into inequalities
y >= x/4 - 4
y < x + 1
The is the graph
The upper line is dotted, and the lower line is continous.
I can not distinguish the graphs, but the solution is the first graph.
