Given data:

The given points are (1,4) and (2,5) .

The given y-intercept is c=-2.

The equation of the slope of the line is,


\begin{gathered} m=(5-4)/(2-1) \\ =1 \end{gathered}

The equation of the line is,


y=mx+c

Substitute 1 for m, and -2 for c in the above equation.


\begin{gathered} y=1(x)-2 \\ =x-2 \end{gathered}

Thus, the equation of the line is y=x-2.
