**Reiny**, Sunday, May 12, 2013 at 12:06amYou 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.
