m = input('Enter the slope of the graph: ');
c = input('Enter the y-intercept c of the graph: ');
x1 = input('Enter x1 value: ');
x2 = input('Enter x2 value: ');
input('The incremented value of x is assumed to be 1, press enter')
x = [x1:x2];
SraightLine = m*x + c; y = SraightLine;

x,y
plot(x,y);
xlabel('x-axis');
ylabel('y-axis');

What is the point of accepting up to four parameters when the value of the parameters will be ignored?

[DGM]

SraightLine = m*x + c; 
y = SraightLine;

Also, what's the point of this variable juggling?

I guess it's fair enough to tempt fools to copy homework laced with subtle(ish) flaws.

If the homework specifically asks for a script, it's best to follow that instruction and use a script file. Misleading the OP (@Taysir Alzoubi) in using a function instead of a script might lead to points being deducted since it doesn't fulfill the assignment requirements.

If you want to use functions for your own practice or if it enhances your solution, you can do so in your own projects. If you're ever unsure, it's a good idea to ask the forumers in MATLAB Answers for clarification.
