Help Translating a BASIC 7.0 Script to BASIC 2.0

I wrote a small program on the C128 to plot a sin function and I'm using basic 7.0-exclusive commands to draw onto the HiRes bitmap (graphics mode 1). I'm wondering if anyone could be able to help me translate it into a script that would run on the C64 with basic 2.0, because POKE's scare me and Google doesn't seem to have my answers. Here is the program:

1 GRAPHIC 1 HiRes Mode

3 SCNCLR Clear graphics screen

5 LOCATE 0,100 : DRAWTO 320,100 Draw horizonal bar

7 LOCATE 160,0 : DRAWTO 160,200 Draw vertical bar

9 LOCATE 0,100 Move to position where function will begin drawing

10 FOR X = 1 TO 320 X axis, display is 320 pixels wide

15 S = X * PI / 160 convert X from degrees to radians

20 Y = INT(100+100*SIN(S)) Scale funtion to screen size

25 DRAWTO X,Y Draw to next point

30 NEXT increment X

I'm new to Commodore BASIC programming so please give me any suggestions to improve/optimize my code. Thanks!
