It wouldnt let me type any more so heres the rest

I get -5 for the gradient and use point C (2,10) to get the equation of the line 5x+y=20

I can post a picture of everything too

Yes

|dw:1441547331269:dw|

C (2,10) ok?

Ok.

now, if it forms a parallelogram, then the left side is |dw:1441547541029:dw|

Oh wait i think you have A and B wrong.

|dw:1441547556565:dw|

Show me my mistake, please.

This is the answer for the first question it asked saying what the graph looks like

So B is on the line on the bottom and is is on the line to the left

yes, just estimate. As long as my logic is Ok, I am ok.

Ok :)

|dw:1441547716564:dw|

agree with me for this?

Yes, I think so

|dw:1441547741256:dw| That is I need a line parallel to 5x+y =20 and passes through B, right?

Same as the line parallel to BC which passes through A (4,0)|dw:1441547992236:dw|

So far, I have 2 new lines. Those are 5x+y = 11 and x + 2y =4
Intersection of them is E(2,1)

|dw:1441548234109:dw|

ok?

Um no I dont think thats right... the book says the answer is (-2,21)

Whatever the book says, I have a proof of it. https://www.desmos.com/calculator/vku2dwjf3q

|dw:1441548556005:dw|

I will send a picture of the graph I made

The slightly shaded in area is what I assumed some of the parallelogram would be

Sorry, its not the neatest graph in the world

Yes, that is the x coordinate of E cannot be negative and y coordinate cannot be exceed 11, right?

Ah no? |dw:1441548896467:dw|

|dw:1441548990858:dw|

And then E would complete it. I know you are saying thats not right, can you explain why?

That's all I know, if it is wrong still. I am sorry for wasting your time. I am done.

Hmm no that makes sense.

I hope you have a nice day, for me its back to maths!
