I am really confused about horizontal stretches, i know in y=2x b= 1/2 and in y=1/2x b=2.

But what if the question was something like y=6/5, what is b then? 5? 1/1.2? Can someone please explain thanks.

??? y= 5? That is not a "stretch" at all because there is no "x". If you meant y= (6/5)x then the horizontal "stretch" would be 5/6. The formula is that if y= ax, then the horizontal stretch is 1/a.

I believe in the case of y = 6/5 x, it is a vertical stretch of 6/5.
