Solve the system of inequalities by graphing

OpenStudy (notamathgenius):

\[4y < -3x \] \[y < \frac{ 3 }{ 4 }x\]

Graph the equations first.. 4y=-3x and 4y=3x..

That's all I can do :(

OpenStudy (yrelhan4):

|dw:1369771874733:dw| it would be something like this with slopes -3/4 and 3/4 respectively..

OpenStudy (notamathgenius):

Ok so when it says solve it by graphing thats what I put, correct?

OpenStudy (yrelhan4):

umm its not solved yet.. but thats what you do first.. graph the equalities.. i'll write the next step in the next post.

OpenStudy (yrelhan4):

next.. you need to remember this.. whenever you have anything like y > x + something or whatever.. i mean a linear equation with y greater than x.. it means you have to gepah the area above the line.. and for a less than sign... y< x + something.. a linear equation. with y less than x .. it basically means the area below the line.. i'll mark the area in the figure in the next post.. you get this btw? http://www.purplemath.com/modules/ineqgrph.htm This can be helpful.. i dont really explain things all that well..

OpenStudy (notamathgenius):

Cheers, for trying though :) you helped me out

OpenStudy (yrelhan4):

|dw:1369772278538:dw| the lines marks the area for line 4y<-3x and the circles kinda thing marks the area for the line 4y<3x..
