For function one, when we have the linear equation:


y=mx+b

The unit rate will be the "m" value, here we have


y=(1)/(4)x+2

Then


m=(1)/(4)

That's the unit rate for function one

To find out the unit rate for function two, we must take two points of the graphic, in a generical way they're are


\begin{gathered} A=(x_a,y_a) \\ B=(x_b,y_b)_{} \end{gathered}

The unit rate will be


m=\frac{y_b-y_a}{x_b-x_a_{}}

I'll use the points


\begin{gathered} A=(3,3) \\ B=(0,1) \end{gathered}

Then the unit rate will be


m=(1-3)/(0-(-3))=(2)/(3)

Hence the unit rate for function two is m = 2/3
