Do you have answer choices?
Yeah they are; (-4,0) (-3,2) (2,-1) (0,6)
we can exclude the first choice since 0>0 is not true in the first equation
(0,6)?
yea

wecan exlude (2,-1) because -1>6 is not true in the first equation
we can exclude (-3,2) since 2>8 is not true in the second equation
or instead of just substituting the points in the the equation, we can graph the two inequalities as see which points are contained in the graph
it would look like this..|dw:1374725241018:dw|
