Which point lies in the solution set for the following system of inequalities? y > x + 4 y > -2x + 2

OpenStudy (ashley_f97):

Do you have answer choices?

OpenStudy (anonymous):

Yeah they are; (-4,0) (-3,2) (2,-1) (0,6)

OpenStudy (anonymous):

we can exclude the first choice since 0>0 is not true in the first equation

OpenStudy (ashley_f97):

(0,6)?

OpenStudy (anonymous):

yea

OpenStudy (anonymous):

wecan exlude (2,-1) because -1>6 is not true in the first equation

OpenStudy (anonymous):

we can exclude (-3,2) since 2>8 is not true in the second equation

OpenStudy (anonymous):

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

OpenStudy (anonymous):

it would look like this..|dw:1374725241018:dw|
