# PicBasic Formula

Started by October 1, 2003
 Can someone tell me or give me an example on how to implement the following formula. My problem is the negative number! a = -20 b = 32 x = Value y=a+bx Thanks in advance, Scott --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

 Scott, It is as easy as changing the formula to y=bx-a Assuming that x is never zero the above works. a= -20 b2 x=5 b*x = 160 y0+ (-20) 0 y0 - 20 = 140 Colin On Wed, 1 Oct 2003 00:39:26 -0400, Scott Lingerfelt wrote: :: Can someone tell me or give me an example on how to implement the ::following ::formula.
