plot graph from array

Hello, I have this array:

Class1 = [1 0; 0.5 1; 0.5 1.5];

How do I go about plotting the 3 points from Class1? If I use

plot(Class1)

I do not get the correct plot.

Assumning column 1 is x and column 2 is y

plot(Class1(:, 1), Class1(:, 2), 'b*-', 'LineWidth', 2, 'MarkerSize', 10);
grid on;
