My code so far is:
x = 0:10;
y = x.^2;
plot(x, y);
The graph shows up as a curved line. How do I change the line type to a dotted line or a dashed-dot line? Also, how do I remove the line (if I want to make a scatterplot)?

Khade - if you wish to use something other than a curved/connected line, then change your call to plot to
plot(x,y,'--');
which will create a dashed line. Use '-.' for a dashed-dot line.
See linespec for more options, and in particular the character specifiers which will help you create a scatter plot.
