Equation of a straight line, how to create an equation with two matrices?

I am a newbie in Matlab I know it will sound silly to most of you guys but I could not solve an example about creating a straight line with the:

x=10, y=1 and x will decrease up to 0, y will increase up to 10. I tried to do something like this:

A=[10,9,8,7,6,5,4,3,2,1];

x=A; B=1:10;

y=B;

for n=1:10 m=y(n)/x(n); plot(x,m*x-(x-x(n))) xlim([0 10]) ylim([0 10])

pause(2)

end

I used pause to see every change in the graph yet the output is something quite different from what I was expecting.

Any suggestions? Again I am a newbie sorry if it is too easy :)

Waiting for answers...Thanks Okan..

Are you trying to draw a line from (10,1) to (0,10)?

line([10,0],[1 10])

Or you mean this:

x=zeros(2,10);
y=zeros(2,10);

x(1,:)=10:-1:1;
y(2,:)=1:10;

line(x,y)

No. I am trying to draw from (10,0) to (0,1)

(9,0) to (0,2)

(9.0) to (0.3) and so on..

[Okan Okyay]

sorry it will be (8,0) to (0,3)

Thank you so much mate. That's the thing what I was trying to get thanks again. I think I have to learn the matrix manipulation before I continue to other parts. Best Regards
