y = 1/2 log(x + 1) - log(2x + 10)

The y-intercept of any graph is the point where x=0.

y = 1/2 log(0 + 1) - log(0 +10)

y = 1/2 log(1) - log(10)

log(1) = 0
log(10) = 1

y = 1/2 (0) - 1

y = -1

That's all there is to it. I'll bet you totally froze when you saw all those logs.

y=(1)/(2)log(x+1)-log(2x+10)\\\\y\ intercept\ for\ x=0:\\\\(1)/(2)log(0+1)-log(2\cdot0+10)=(1)/(2)log1-log10=(1)/(2)\cdot0-1=-1\\\\Answer:y=-1,\ the\ point\ is\ (0;-1).
