Question

How do I find the coordinates of the vertices of the figure formed by each system of inequalities:
y+x ">=" -9
y ">=" x-7
2y + x"<=" 16

Answer 1

Do you know how to graph inequalities?

Answer 2

no

Answer 3

Do you know how to graph straight lines ?

Answer 4

Algebra is very tough for me...what do you mean by straight lines? Yes for basic graphing, no for inequalities if that makes sense...

Answer 5

So if i tell you graph x+y=9 you know how to do it?

Answer 6

yes, sort of...using an x/y table?

Answer 7

Yeah whatever method, so if you want to graph the first inequality
x+y>=9, so first you draw the graph of x+y=9 which looks like
