The point $\left(- 4 , 0\right)$

#### Explanation:

$x$ intercept is when $y = 0$

substitute $0$ instead of $y$ and then solve for $x$

$- 3 x + 8 \left(0\right) = 12$
$- 3 x = 12$
$x = - 4$

The point is $\left(- 4 , 0\right)$

The x-intercept= -4
$\left(- 4 , 0\right)$

#### Explanation:

To find the x-intercept of a graph, make $y = 0$

$- 3 x + 8 y = 12$

$- 3 x + 8 \left(0\right) = 12$

$- 3 x = 12 \text{ } \leftarrow \div - 3$

$x = - 4$
