Plotting one point requres a marker, and plotting a line requires at least two vectors of the same size.

Two options, depending on the result you want —

x = [6000,9375];
y = 10;

figure
plot(x,y,'pr')
title('x by y')
xlabel('x')
ylabel('y')

x = [6000,9375];
y = 10*ones(size(x));

figure
plot(x,y,'red')
title('x by y')
xlabel('x')
ylabel('y')

And of course, you can plot both markers and lines of various kinds connecting them.
