Since the graph is a line, we can use the linear equation y = mx + b to represent it.
In order to find the values of m and b, we can use two points that are on the line (therefore are solution to the equation).
Using the points (0, 5) and (1, 6), we have:
![\begin{gathered} y=mx+b \\ (0,5)\colon \\ 5=0m+b\to b=5 \\ (1,6)\colon \\ 6=m+b \\ 6=m+5 \\ m=6-5=1 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/v8otdk6hwl7p7spmoj7r64k420jemgxuz1.png)
So the equation is:
