You have an infinite number of points which are a solution to the given system.
from the first:
y > (4/5)x + 4
sketch y = (4/5)x + 4 , using a dotted line
shade in the region ABOVE that line
from the 2nd:
y < (8/3)x + 8
draw a dotted line y = (8/5)x + 8
shade in everything BELOW that line
Any point in the region shaded by both will be a solution
e.g. (5,5) works for both inequations
(10,0) works for both inequations.
