Emaan plots one point at (0,4):
This is correct, he found the y-intercept:
[tex]y(0)=\frac{2}{3}(0)+4=0+4=4[/tex]and a second point 2 units right and 3 units up at (2,7). let's check:
[tex]\begin{gathered} x=2 \\ y(2)=\frac{2}{3}(2)+4 \\ y(2)=\frac{4}{3}+4=\frac{16}{3} \end{gathered}[/tex]This is the error, because for x = 2, y = 16/3
