From GG $a=2, b=3$ and $c=3$, i.e. $y=\frac{2 x+3}{3 x-2}$

$y=\frac{a x+b}{c x-2}$

Sub $(1,5)$ and $(-8,0.5)$ into equation,

$a+b-5 c=-10-(1)$

$8 a-b-4 c=1 \ldots(2)$

After transformation, the translated curve is $y=\frac{a(x-1)+b}{c(x-1)-2}$.

Substitute $(0,-0.2)$, we get $5 a-5 b+c=-2$

From GG $a=2, b=3$ and $c=3$, i.e. $y=\frac{2 x+3}{3 x-2}$
