Question

For this I already did the first part and I got f(x)=2.5x+1so can you help me with the second part

Answer 1

`\begin{gathered} x_1=0,y_1=1,x_2=2,y_2=6 \\ \text{slope,}\Rightarrow m=(y_2-y_1)/(x_2-x_1) \\ m=(6-1)/(2-0) \\ m=(5)/(2)(slope) \\ y-y_1=m(x-x_1) \\ y-1=(5)/(2)(x-0) \\ 2y-2=5x \\ y=(5)/(2)x+2 \\ y-\text{intercept is }\Rightarrow2 \end{gathered}`
