"x" and "y" are not defined in the code. Since you have used "To Workspace" block in simulink, your variables are saved in the variable "out". Here is an example of what you can do to get those values:
out = sim('Mass_Spring_System2_simulink.slx');
displacement = out.x.Data;
timeArr = out.x.Time;
plot(timeArr, displacement);

Hi Soumya,
Based on my understanding, you are encountering an error stating "Unrecognized function or variable 'x'" while running a Live Script.
From the attached screenshot, it appears that you are attempting to use plot(x) without having defined the variable 'x'. Similarly, you haven't defined the variable 'y', which is used in plot(y). Please replace 'x' and 'y' with the variables you intend to plot.
Refer to the following MATLAB documentation to know more about 'plot':
