if x = [1 2 3 ...... 10]
y1=[0.5 1.7 1.75 1.9 2 2.1 2.4 2.6 2.7 2.9 ]
y2=[0.7 1.8 1.9 2 2.3 2.5 2.7 2.8 2.9 3]
how can I make save (x,y) and (x,y1) then do load it
then plot it

Try this:
x = 1:10;
y1=[0.5 1.7 1.75 1.9 2 2.1 2.4 2.6 2.7 2.9 ]
y2=[0.7 1.8 1.9 2 2.3 2.5 2.7 2.8 2.9 3]
save('XYvectors.mat','x','y1','y2')
D = load ('XYvectors.mat');
x = D.x;
Y1 = D.y1;
y2 = D.y2;
Use whatever file name you want.

There are certainly different ways to do so.
E.g.:
x = 1:1:10;
y1=[0.5 1.7 1.75 1.9 2 2.1 2.4 2.6 2.7 2.9 ];
y2=[0.7 1.8 1.9 2 2.3 2.5 2.7 2.8 2.9 3];
save('filename', 'x', 'y1', 'y2') ;
data = load('filename');
plot(data.x, data.y1);
plot(data.x, data.y2);

Not sure whether I got your point.
Do you want to know how to plot both traces in one figure or something else?

For plotting multiple traces in one diagram, use the "hold" command in order to prevent the plot from being cleared:
plot(data.x, data.y1);
hold on;
plot(data.x, data.y2);
