The answer is -11 or +11

Step-by-step explanation:

The y-intercept of f(x) is the value of f(x) when x=0,

f(x) = -5 when x=0

The equation of g(x) is,


\begin{gathered} \text{Slope of g(x)=}(y_2-y_1)/(x_2-x_1)=(3-2)/(-6--8)=(1)/(2) \\ Theequationofg(x)is;y-y_1_{}=2(x-x_1) \\ y-2=(1)/(2)(x--8) \\ y-2=((x+8))/(2) \\ \text{The y- intercept of g(x) is the value of g(x) when x=0,} \\ y-\text{intercept of g(x)=6} \\ \end{gathered}

So, The difference between y-intercept of f(x) and that of g(x) = -5-6=-11 or 6 - -5= 11
