**math am i correct**

I didnt notice until now, but oyu moved teh terms wrong. original: x+4y=8 -> 4y = -x + 8 Divide each side by 4 to isolate y: y = -(1/4)x + 2 In teh form y = mx + b (y-intercept form), m is the slop. So slope = -1/4.
*October 4, 2009*

**math am i correct**

You have to divide both sides by 4 to isolate y, then the slop will be the coefficient of x.

By the way what ive got so far is: gcd(a,b) = d, so d|a and d|b, so d|(a+b). Since d|(a+b) and d|a d <= gcd(a,b+a), which means gcd(a,b) <= gcd(a,b+a). Its the other half that im stumped for.

This is a problem concerning GCD. I need to prove gcd(a,b) = gcd(a,b+a). I always get like like halfway then hit a roadblock (e.g. i can prove gcd(a,b) <= gcd(a,b+a) but not gcd(a,b) >= gcd(a,b+a).
