Notice that all the options contain the term
[tex]\frac{5}{7}x[/tex]
Setting x=35, we obtain
[tex]\frac{5}{7}(35)=5\cdot5=25[/tex]
Finally,
[tex]30=25+5[/tex]
Then, the answer is
[tex]\begin{gathered} y=\frac{5}{7}x+5 \\ \text{set x=35} \\ \Rightarrow y=\frac{5}{7}\cdot35+5=25+5=30 \end{gathered}[/tex]
Option D is the answer, y=5x/7+5.
Notice that all the options have the same slope as that of the line y=5x/+10
