y < -4x/5 + 6 ........................................... 1
for x = 0,
y = 4/5 (0) + 6
y = 6
for y = 0,
0 = - 4x/5 + 6
-6 = -4x/5
6 x 5 = 4x
30 = 4x
x = 30/4
x = -7.5
y >x - 4 ...................................................... 2
when y = 0,
0 = x - 4
x = 4
when x = 0
y = 0 - 4
y = -4
The solution to the inqualities is the unshaded triangle ABC.
