How to plot point coordinates with connecting lines in between.

So I have a set of point coordinates with a line connects between them, I am not sure about the command to plot those points.
This is what I have:
x(1) = (-5.3185, -2.302585);
x(2) = (-10.0332, -4.6052);
x(3)= (-14.6496, -6.9078);
x(4)=(-19.2959,-9.2103);
plot(x(1),x(2),x(3),,x(4), '*-')
Thanks for any input!

x(1) refers to only the first element in some variable x, and similarly, x(2) refers to only the second element. So you can't assign two values to x(1) as you've tried to do with
x(1) = (-5.3185, -2.302585);
One way to do it is to assign x and y values separately:
x = [-5.3185 -10.0332 -14.6496 -19.2959];
y = [-2.302585 -4.6052 -6.9078 -9.2103];
plot(x,y, '*-')

that's not matlab syntax. Reading the documentation of "plot" is a good idea here. Type doc plot (enter)
Anyway, you should build vectors with the abscissae and the ordinates (using square parentheses)
x = [-5.3185 -10.0332 -14.6496 ...];
y = [...];
and then simply
plot(x,y)
or
plot(x,y,'.-')
