#### Answer

$(0, 3)$; $2$; $5$

#### Work Step by Step

The line $y=\frac{2}{5}x+3$ has a slope of $\frac{2}{5}$ and a y-intercept of $3$. To graph this line, perform the following steps: (1) Plot the y-intercept point $(0, 3)$. (2) From $(0, 3)$, move 2 units upward (the rise) then move 5 units to the right (the run). These movements will lead to the point $(5, 5)$. (3) Connect the points $(0, 3)$ and $(5, 5)$ using a line. Thus, the missing expressions in the given statements are: $(0, 3)$; $2$; $5$
