help? best anwser gets medal
It's already done :)
you have to do shading
Ok, Then first we'll plot the equation : \[2.75y=x+6\] put y=0, you'll get x=-6 put x=0, y=6/2.75=2.18 Do you get this @hali12 ?
no
We have the equation \[2.75y=x+6\] put y=0 \[0=x+6\] so \[x=-6\] Do you get this?
yes
is that the anwser?
no, we have just begun. now put x=0, and find the value of y
oh
then what? idk how tp do that
\[2.75y=0+6\] find the value oy, divide both sides by 2.75. What would you get?
-2.18
\[y=6\div 2.75\]
its -6
It's +6 \[2.75y=x+6\] x=0 \[2.75y=6\]
oh okay thanks
Now we got two points A ( -6, 0) B(0, 2.18) Let's mark this on graph and then make the line|dw:1363625931821:dw| Now we need to shade the portion of \[y<\frac{x+6}{2.75}\] Are you here?
ya
Let's check if (0, 0 ) is part of the solution \[0<\frac{0+6}{2.75}\] \[0< 6/2.75\] This is true so right side potion of the line is our region.|dw:1363626216180:dw|
