Because you defined x as a looping variable, after the loop is completed, x is equal to just the last value in the loop. Instead, do this
x = linspace(1,2,10);
new = 10*x;
plot(x,new,'b*-')

A for loop assigns the loop control variable each column of the expression in turn. After the loop it has the last value it was assigned.
So after the loop your x is scalar, not the entire list of values.
