$A coordinate grid showing the line y = two-thirds x plus 1, with a step of run 3 and rise 2 landing exactly on the lattice point (3, 3), and a fainter step of run 1 landing between gridlines.$

For the line $y = \frac{2}{3}x + 1$ , you start at the $y$ -intercept and want to land exactly on a gridline intersection. How far right should you step?
