Hello. How are you guys doing?
I don't have idea about how to graph in excel or word.. could you please help me to graph these inequalities?
1) 3x+4y>4 and x-2y<-1
2) x/2+y/4<1
3) 4x+1y ≥. 26 and 2x+y ≥18
4)x+5y≥ and x+y ≥ 5
thank you.

I did not know word had a graphing package? I think you mean graph in excel and paste such charts into Word.
This makes no sense.
Most of these are in intercept form. All you need to do is find the x-intercept by making y = 0 and then find the y-intercept by making x = 0.
Here's an example.
x=0:
$\displaystyle 3\times 0 +4y>4$
$\displaystyle 0 +4y>4$
$\displaystyle 4y>4$
$\displaystyle y>1$
This means you have a point (0,1)
y=0:
$\displaystyle 3x+4\times 0>4 $
$\displaystyle 3x+ 0>4 $
$\displaystyle 3x>4 $
$\displaystyle x>\frac{4}{3} $
This means you have a point $\displaystyle \left(\frac{4}{3},0\right)$
Now join the points and find the required region.
Thank you pickslides... could you please help me to graph those inequalities in excel??? I already solved the inequalities, but I don't know how to graph them, for instance, this is how I solved the following inequality:
4x+1y ≥26
2x+y ≥8
X+1/4y=6.5
X+1/2y=9
-1/4y=-2.5
Y=10
X=9-5=4
And you were right about inequality number 4, i forgot to type a number..
3) x+5y≥ 9 and x+y ≥ 5
