Hi Hailey,
I understand that you are getting difficulty in plotting 2D graphs in MATLAB. And from the given data I am assuming that you want to plot x1, x2, x3, x4 against t and to plot all these on same graph you can use "hold on" and "hold off".
% you can use your own data
t = linspace(1, 100, 10);
x1 = linspace(1, 10, 10);
x2 = linspace(11, 20, 10);
x3 = linspace(21, 30, 10);
x4 = linspace(31, 40, 10);
plot(t,x1);
hold on
plot(t,x2);
plot(t,x3);
plot(t,x4);
hold off
For more information on plots you can refer below documentation:

Hope it helps!
