Do you mean that you want to graph an equation (y+mx+b)?

To change the value of x over and over again you can either use DO-LOOP or FOR-NEXT. To graph it you have to be careful, you have to flip it over. Normally as you go higher and higher on a graphi the Y coordiante gets higher, on a computer screen it gets lower.

Just use a FOR counter, ie.

FOR x = 1 TO 10
Result = x + 1
PRINT "If x = ";x;" then the result is ";result
NEXT
