Plotting a function with polyfit and a for loop

I need to use polyfit and a for loop to create a plot in Matlab. However, here's the catch: The values that need to be graphed need to be taken out from an inputted matrix. For example: the matrix is: [1 2 3; 4 5 6; 7 8 9; 10 11 12]. But I only need to graph the first two rows as such: the first row are the x values and the second row are the y values. And then create another graph with the third row being the x values, and the fourth row being the y values. But this also has to work for an unlimited number of inputs or rows. Any help is appreciated!

Here is one way
M = [1 2 3; 4 5 6; 7 8 9; 10 11 12];
nrows = size(M,1);
for nr = 1:2:nrows
figure
x = M(nr, :);
y = M(nr+1,:);
plot(x,y)
end
