How do you call plot3 to plot a line through points (1,2,3), (4,5,6), and (7,8,9)?

Use plot3([1 4 7], [2 5 8], [3 6 9]) to connect the points with a 3D line.

How can you change the color and style of the 3D line in plot3?

Add a format string like 'r--' to plot3, e.g., plot3(x, y, z, 'r--') for a red dashed line.
