**Reiny**, Monday, April 13, 2009 at 6:26pmsince you are talking about x and y intercepts you should look at your relation as

20x + 34y ≥ 240 rather than using a and b

I usually use the x and y intercepts, since in most cases you can do them in your head.

e.g. if y = 0, x = 12

if x = 0, y = appr. 7 (actually 7.06)

so you quickly have two points that determine your line.

If the equation is in the form

y = mx + b, I mark the y-intercept, then step off to the next point by using the slope.

e.g. y = (3/4)x + 1

mark (0,2), from that point move to the right 4, then up 3 and you got your two points for the line. Real easy.
