Solving linear equations simultaneoulsy.

I have a vector of m and a vector of c values for a set of linear expressions. I have a value for m and c for a single expression. What I want to do is solve the linear equation for all the m and c values. How would I simultaneously solve this expression with every one in the two corresponding vectors.

i.e.

y=2x +5
m=[3 4 5]
c=[2 3 6]

y=2x+5 with y=3x +2

y=2x+5 with y=4x+3

y=2x+5 with y=5x+6

x=(5-c)./(m-2);
y=2*x+5;

This is my for loop.

   for gra=m && yint=c
        x = (gra-c)./ (m-2)
        y = m.*x+c
    end

Although I cant get it to work.

What's wrong with my original proposal, which doesn't use any loops?

[Giuseppe]

I have a vector with different values for y=2x+5

[Matt J]

   for i=1:length(gra)

        x{i} = (gra(i)- c)./ (m-yint(i));
        y{i} = m.*x{i}+c;
    end
