$\frac{35}{4}$

#### Explanation:

slope is always "rise over run".
$\frac{\Delta Y}{\Delta X}$ = $\frac{65 - 30}{8 - 4}$ = $\frac{35}{4}$

The slope of the line passing through $\left(4 , 30\right)$ and $\left(8 , 65\right)$ is $\frac{35}{4}$.

#### Explanation:

The formula for the slope of a line when two points $\left({x}_{1} , {y}_{1}\right)$ and $\left({x}_{2} , {y}_{2}\right)$ are given is $m = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$ where $m$ is the slope.

Using this formula:
$m = \frac{65 - 30}{8 - 4}$
$m = \frac{35}{4}$
