## bimbim2697 4 years ago Help please graph each linear inequality y>3x-4 x+y<-3 x-2y>-1 x =>-4 y<2 y<x 3x+5<14

1. anonymous

First graph each as "equality". Depending on the inequality, all points above or below that line will satisfy the inequality.

2. anonymous

For example, take y<2. Graph the equality y=2. That will be a horizontal line at y=2. All points below that line will satisfy y<2.

@GT Can U show me wht u mean by tht ?

That line is y=2. So, all points below that would be y<2.

All those points in that region satisfy the inequality.

im like slowly getting it hoe eud u find y<x

That line is y=x. So, for y<x, all points below that line would satisfy that inequality.

@gt how do i determine of the ordered pair is a solution of the linear inequality 7x+2y>-5,(-1,1) x-y<=3, (2,-1)

14. anonymous

replace x by -1 and y by 1 and see if it works

15. anonymous

$7\times (-1)+2\times 1=-7+2=-5$ and now we have to be careful because $-5<-5$ is not true, so no for the first one

16. anonymous

second one replace x by 2, y by -1 and get $2-(-1)\leq 3$ $3\leq 3$ and that one is true

17. bimbim2697

What abt the last one ?

18. anonymous

that was the last one. that was $x-y\leq 3$ for $(2,-1)$

19. anonymous

answer is yes, i does satisfy that inequality

20. bimbim2697

oh my first set of questions

21. bimbim2697

y>3x-4 x+y<-3 x-2y>-1 x =>-4 y<2 y<x 3x+5<14
