Let the two points in the graph are (0,7) and (1,3).

Then, the slope of the line is,


\begin{gathered} m=(y_2-y_1)/(x_2-x_1) \\ m=(3-7)/(1-0) \\ m=-4 \end{gathered}

Use the equation y=y1=m(x-x1) to find the equation of the line.


\begin{gathered} y-7=-4(x-0)\text{.} \\ y-7=-4x \\ y=-4x+7 \end{gathered}

Therefore, the equation of the line is y=-4x+7.
