@Warda Panondi: have you read the plot documentation? It clearly explains the line specification options. Not only that, the documentation is easy to find: it is installed on your computer with MATLAB itself, so you just need to type
doc plot
or
help plot
The help is also online: this is the very first link provided by a major internet search engine:
Reading the documentation yourself is a lot faster than posting questions on forums and then waiting for random strangers to go and read that documentation on your behalf.

The ‘-r’, ‘-g’, and ‘-b’ tell the plot function you are using to plot ‘t,AC(3,:)’ with a red solid line, ‘t,AC(2,:)’ with a green solid line, and ‘t,AC(1,:)’ with a blue solid line.

Warda - the strings are referring to the line style, marker, and colour (see 2D line plot spec). The 'r', 'g', and 'b' are referring to the colour of the plots: red, green, blue. The '-' indicates that a solid line should be drawn.
