We can see from the graph that the solution for y is y = 2. Then, to find exactly the value for x, we can substitute y = 2 on either equation to get the following:

[tex]\begin{gathered} y=2 \\ \Rightarrow5(2)=8x+8 \\ \Rightarrow10-8=8x \\ \Rightarrow\frac{2}{8}=x \\ x=\frac{1}{4} \end{gathered}[/tex]

therefore, the point of intersection is (1/4, 2)
